Source Code Search Php | Ajax Live Search

#12. Search Data using PHP and MySQL database.

The PHP File

The page on the server called by the JavaScript above is a PHP file called “livesearch.php”.

The source code in “livesearch.php” searches an XML file for titles matching the search string and returns the result:

$xmlDoc=new DOMDocument();

$xmlDoc->load(“links.xml”);

$x=$xmlDoc->getElementsByTagName(‘link’);

//get the q parameter from URL

$q=$_GET[“q”];

//lookup all links from the xml file if length of q>0

if (strlen($q)>0) {

$hint=””;

for($i=0; $i<($x->length); $i++) {

$y=$x->item($i)->getElementsByTagName(‘title’);

$z=$x->item($i)->getElementsByTagName(‘url’);

if ($y->item(0)->nodeType==1) {

//find a link matching the search text

if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q)) {

if ($hint==””) {

$hint=”

” .

$y->item(0)->childNodes->item(0)->nodeValue . “”;

} else {

$hint=$hint . ”

” .

$y->item(0)->childNodes->item(0)->nodeValue . “”;

// Set output to “no suggestion” if no hint was found

// or to the correct values

if ($hint==””) {

$response=”no suggestion”;

} else {

$response=$hint;

//output the response

echo $response;

?>

If there is any text sent from the JavaScript (strlen($q) > 0), the following happens:

  • Load an XML file into a new XML DOM object
  • Loop through all
    <br /> elements to find matches from the text sent from the JavaScript<br />
  • Sets the correct url and title in the “$response” variable. If more than one match is found, all matches are added to the variable
  • If no matches are found, the $response variable is set to “no suggestion”

Searching PHP source code made easy

Search PHP source code for function & method calls, variable assignments, classes and more directly from PHP.

Result


require ‘conn.php’;$query = mysqli_query($conn, “SELECT * FROM `blog` WHERE `title` LIKE ‘%$keyword%’ ORDER BY `title`”) or die(mysqli_error());while($fetch = mysqli_fetch_array($query)){?>

In this tutorial we will create a Simple Search Box using PHP. PHP is a server-side scripting language designed primarily for web development. Using PHP, you can let your user directly interact with the script and easily to learned its syntax. It is mostly used by newly coders for its user-friendly environment.

So Let’s do the coding…

First, you have to download & install XAMPP or any local server that can runs PHP scripts. Here’s the link for XAMPP server https://www.apachefriends.org/index.html.

And this is the link for the jquery that i used in this tutorial https://jquery.com/.

Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Open your database web server then create a database name in it db_box. After that, click Import then locate the database file inside the folder of the application then click ok.

Or, you can also create the sample table and insert a sample data in your database by copying and pasting the code below at SQL tab in your PHPMyAdmin.

`blog_id` int(11) NOT NULL PRIMARY KEY AUTO_INCRMENT,(1, ‘The Little Gingerbread Man’, ‘Once upon a time there was an old woman who loved baking gingerbread. She would bake gingerbread cookies, cakes, houses and gingerbread people, all decorated with chocolate and peppermint, caramel candies and colored frosting.’),(2, ‘The Halloween House’, ‘Now Suzie\’s moved in–she\’s only 4–along with her brother, her father and mother, and little Picador. He\’s their dog. Well, maybe half a dog. He\’s a Chihuahua, as small as they come.\r\n\r\nSuzie\’s room is in the attic. It\’s no fun. With a high ceiling, cold and gloomy, and shadows that run halfway up the walls. Suzie hides under the blanket. Picador too. Come on, he\’s no guard dog.’);

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it

conn.php

.


$conn = mysqli_connect(‘localhost’, ‘root’, ”, ‘db_box’) or die(mysqli_error());if(!$conn){die(“Error: Failed to connect to database”);}?>

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as

index.php

.

Read search engine php mysqli source code for more information.

A search engine is important functionality required in tools today. It allows people to search for information on the Internet. A search engine can be created easily by using open source technologies like PHP and MySQL.

Here, in this article, we will focus on the make use of the most basic code. This will remove the need of going through the complex SQL queries.

The example placed here will show a live search. In livesearch.php, the search engine PHP MySQL source code searches for an XML file for the titles. The search engine script of a free site is built with the help of PHP and Ajax. A site search engine script uses MySQL to store the website’s indexed pages.

The MySQL extension source code is situated in the PHP extension directory. Now, you need to look for a MySQL database with the sample data and then connect it. Also, search for PHP which is the main file of the search engine, where the user can input script.js. This file consists of javascript functions to perform the AJAX requests. Here is the latest info on build a custom search engine with php 2.

Building a custom search engine has many uses. For example, we often face the difficulty to find good news sources, this can be solved by a custom search engine which made for only that purpose. his might get you wondering how to build a custom new search engine. You can do this for pretty much any platform even something as complicated as hybris, there is an advanced search for hybris available too. Once the search engine is built it is now time to add a stylish search box in HTML, this will be the UI available to the site visitors to interact with your search engine. Before you style the search bar it is very important to know how to make a search bar in HTML. It’s often hard to find a place where you can make a custom search engine and get the UI for the search bar all in the same place, but there are a few places like that and Expertrec custom search is one of the good ones among them. It’s pretty simple to set this up. All you gotta do is to get your Expertrec site id and you are good to go.

Sometimes you might want to create a search engine that searches the entire web and that too in specific platforms for example you might think of how to create search engine like google in php. However adding a google custom search engine for you website is a pretty easy task as seting up this does not require much effort. Although if your requirement need igh degree a customisation then its best to get the google custom search code in html. Making a custom search engine as said before has a lot of benefits and advantages going one of them is the convenience of having an internal search engine for private networks. Another very good use of having a custom search engine is to have one for the doucmentation section of your site. This can be pretty messy often but you have to provide your visitor an option to easily navigate them. Hence having a documentation search engine for your website is another great applicaiton of a custom search engine.

Here is more information on how to search for settings in a single page app menu.

Want to build a powerful Live search box using PHP, MySQL, and Ajax?

If yes! Then this guide will help you explore how to create a powerful live search.

Our goal is to provide you with an itemized step-by-step guide so that you can create a Live search box for yourself, understand the technical aspects of building a live search feature, and also outrank other websites.

The live search feature, or AJAX search, refers to the search engine beginning to display results as you type text into the input field. You can view search results without bringing up a display page, thanks to this feature . As a result, people may locate what they’re seeking more quickly.. The development of AJAX search uses JavaScript (jQuery), MySQL, PHP, and AJAX.

Even Google, the most popular search implements the idea of Live search on its page:

Definition and Usage

The show_source() function outputs a file with the PHP syntax highlighted. The syntax is highlighted by using HTML tags.

The colors used for highlighting can be set in the php.ini file or with the ini_set() function.

show_source() is an alias of highlight_file().

Note: When using this function, the entire file will be displayed – including passwords and any other sensitive information!

AJAX Live Search

The following example will demonstrate a live search, where you get search results while you type.

Live search has many benefits compared to traditional searching:

  • Results are shown as you type
  • Results narrow as you continue typing
  • If results become too narrow, remove characters to see a broader result

Search for a W3Schools page in the input field below:

The results in the example above are found in an XML file (links.xml). To make this example small and simple, only six results are available.

Technical Details

Return Value: If the return parameter is set to TRUE, this function returns the highlighted code as a string instead of printing it out. Otherwise, it returns TRUE on success, or FALSE on failure
PHP Version: 4+
Changelog: As of PHP 4.2.1, this function is now also affected by safe_mode and open_basedir. However, safe_mode was removed in PHP 5.4.

PHP 4.2 – The return parameter was added.

❮ PHP Misc Reference

You can create an HTML form that allows you to search records in your MySQL Tables and print the results in a web browser.

In these project we use LIKE and wildcards for the query so that users do not have to have an exact match for results to be provided.

".$row["age"]." ".$row["gender"].""; } } else { echo "0 records"; } $conn->close(); ?>

Database operations in PHP are a very crucial thing that is especially needed in CRUD (Create, Read, Update and Delete) operations.

In this article, we will discuss the Read part i.e. data fetching from database.

There are two ways to connect to a database using PHP. They are as follows.

  1. MySQLi (“i” stands for improved)
  2. PDO (PHP Data Objects)

MySQLi vs PDO: Both the ways are really good but there is only one difference between the two methods, PDO can work on 12 different database systems whereas MySQLi works with MySQL databases only.

Connecting to a Database:

  • MySQLi Object-Oriented

    $conn = new mysqli($servername, $username, $databasename)

  • MySQLi Procedural

    $conn = mysqli_connect($servername,
    $username, $password, $databasename);

  • PDO

    $conn = new PDO(“mysql:host=$servername;dbname=myDB”,
    $username, $password, $databasename);

Executing Queries: After connecting to the database we need to run queries to fetch data. In Read operations, we will use only select queries to fetch data from the database.

Close Connection: After the fetching is performed, you should close the connection to the database using the close() function.

$conn->close();

Sample Database

Create Table in the database:

CREATE TABLE `Student Details` (
`Roll_No` int(11) NOT NULL,
`Name` varchar(255) NOT NULL,
`City` varchar(255) NOT NULL,
`Age` int(11) NOT NULL,
PRIMARY KEY (`Roll_No`)
);

PHP show_source() Function

Example

Using a test file (“test.php”) to output the file with the PHP syntax highlighted:




show_source(“test.php”);?>

show_source(“test.php”);

?>

The browser output of the code above could be (depending on the content in your file):




echo (“test.php”);?>

echo (“test.php”);

?>

The HTML output of the code above could be (View Source):





<html><body>

<?php


echo (


"test.php"


);


?>

</body></html>

<html>

<body>


<?php

Searching

To search a file, use the

search

method. Its only parameter may be either a string containing a valid filename or an instance of

\Permafrost\PhpCodeSearch\Support\File

.

To search a string instead, use the

searchCode

method.

The search methods return an instance of

Permafrost\PhpCodeSearch\Results\FileSearchResults

, which has a

results

property.

Each

result

is an instance of

Permafrost\PhpCodeSearch\Results\SearchResult

with the following properties:


  • node

    – the specific item that was found


    • node->name(): string

  • location

    – the location in the file that the item was found


    • location->startLine(): int

    • location->endLine(): int

  • snippet

    – a snippet of code lines from the file with the result line in the middle


    • snippet->toString(): string

  • file()

    (method) – provides access to the file that was searched

Searching

To search through the code in a string or file, use the

Searcher

class:

use Permafrost\PhpCodeSearch\Searcher; $searcher = new Searcher();

To search a file, use the

search

method, and the

searchCode

method to search a string of code.

$searcher ->functions([‘strtolower’, ‘strtoupper’]) ->search(‘./file1.php’); $searcher ->variables([‘/^one[A-Z]$/’]) ->searchCode(‘

When searching using any of the available methods, regular expressions can be used by surrounding the name with slashes , i.e.

/test\d+/

.

Variable names

To search for variables by name, use the

variables

method.

$results = $searcher ->variables([‘twoA’, ‘/^one.$/’]) ->searchCode(‘

results as $result) { echo “Found ‘{$result->node->name()}’ on line {$result->location->startLine}” . PHP_EOL; }

Functions

To search for function calls or definitions, use the

functions

method.

// search for references AND definitions for ‘strtolower’ and/or ‘myfunc’ $searcher ->functions([‘strtolower’, ‘myfunc’]) ->search(‘file1.php’);

Method calls

To search for a method call by name, use the

methods

method.

Method call nodes have an

args

property that can be looped through to retrieve the arguments for the method call.

$results = $searcher ->methods([‘/test(One|Two)/’]) ->searchCode(‘

testOne(“hello world 1”); ‘. ‘ $obj->testTwo(“hello world”, 2); ‘. ” ); foreach($results->results as $result) { echo “Found ‘{$result->node->name()}’ on line {$result->location->startLine}” . PHP_EOL; foreach($result->node->args as $arg) { echo ” argument: ‘{$arg->value}'” . PHP_EOL; } }

Static calls

To search for static method or property calls, use the

static

method.

Valid search terms are either a class name like

Cache

, or a class name and a method name like

Cache::remember

.

$searcher ->static([‘Ray’, ‘Cache::has’, ‘Request::$myProperty’]) ->search(‘./app/Http/Controllers/MyController.php’);

Classes

To search for either a class definition or a class created by the

new

keyword, use the

classes

method.

$searcher ->classes([‘MyController’]) ->search(‘./app/Http/Controllers/MyController.php’);

Variable assignments

To search for a variable assignment by variable name, use the

assignments

method. Note: The should be omitted.

$searcher ->assignments([‘myVar’]) ->search(‘./app/Http/Controllers/MyController.php’);

Results without code snippets

To return search results without associated code snippets, use the

withoutSnippets

method:

$searcher ->withoutSnippets() ->functions([‘strtolower’]) ->search(‘file1.php’);

The following files need to be created in the htdocs folder, which are categorically located at C:/xampp/htdocs:

Creating Search Form and Related Files In this step,

We will create the following files:

Search.php

Name the file search.php while creating. This is a main file of a search engine, where the user can view the result and input data. Put the code below into it by simply pasting it.


<br /> Live Search using AJAX<br />






Example:

db.php

This file contains the necessary details for establishing a database connection. Create a file named “db.php” and insert the following code:

ajax.php

This file acts as the main source for generating AJAX requests to the server and retrieving the results. Make a file called “ajax.php” and put the following code in it:


'; // Fetch the results from the database. while ($Result = MySQLi_fetch_array($ExecQuery)) { ?>

  • script.js

    This file contains JavaScript functions that perform AJAX requests. Add the following code to the “script.js” file you just created:


    // Retrieve the value from "ajax.php". function fill(Value) { // Assign the value to the "search" div in "search.php". $('#search').val(Value); // Hide the "display" div in "search.php". $('#display').hide(); } $(document).ready(function() { // When a key is pressed in the "Search box" of "search.php", this function will be called. $("#search").keyup(function() { // Assign the search box value to a JavaScript variable named "name". var name = $('#search').val(); // Validate if "name" is empty. if (name == "") { // Assign an empty value to the "display" div in "search.php". $("#display").html(""); } // If the name is not empty. else { // Initiate an AJAX request. $.ajax({ // Set the AJAX type as "POST". type: "POST", // Send data to "ajax.php". url: "ajax.php", // Pass the value of "name" into the "search" variable. data: { search: name }, // If a result is found, this function will be called. success: function(html) { // Assign the result to the "display" div in "search.php". $("#display").html(html).show(); } }); } }); });

    style.css

    This file contains styling elements for the search engine. Add the following code to a file called “style.css“:


    a:hover { cursor: pointer; background-color: yellow; }

    1. The search engine is now ready for testing. To proceed, follow these steps:

    localhost:8080/search.php

    1. Enter some text in the search field to perform a search in the database.

    Note that as you type, the text will be sent to the script.js file, which will then forward the request to ajax.php. In ajax.php, a JavaScript function named “fill()” will process the fetched results and display them in the “display” div of the search.php file.
