Submitted by razormist on Thursday, January 2, 2020 - 22:02.

In this tutorial we will create a Eliminate Duplicate Entry In Arrays using PHP. This code can eliminate multiple duplicate array when the user click the button. The code use PHP array_unique() a special built-in function that is specialize in finding and searching for a possible duplicate in order to instantly delete that objects This is a user-friendly kind of program feel free to modify it. We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites and it has a modern technology that can easily be use by the next generation.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating The Interface

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.

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">PHP - Eliminate Duplicate Entry In Arrays</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-8">
                        <form>
                                <div>
                                        <label>List of Array</label>
                                        <div id="result"></div>
                                </div>
                        </form>
                </div>
                <div class="col-md-4">
                        <button type="button" class="btn btn-primary" id="delete"></span> Eliminate Duplicate</button>
                </div>
        </div>
</body>
<script src="js/jquery-3.2.1.min.js"></script>
<script src="js/script.js"></script>
</html>

Creating the Main Function

This code contains the main function of the application. This code will eliminate duplicate array when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as shown below. array.php

<?php
        $array = array("Meliodas", "Merlin", "Ban", "Ban", "Escanor", "Escanor", "Escanor");
        if(ISSET($_POST['res'])){
                echo "<pre>";
                print_r($array);
                echo "</pre>";
        }
        
?>

eliminate.php

<?php
        $array = array("Meliodas", "Merlin", "Ban", "Ban", "Escanor", "Escanor", "Escanor");
        if(ISSET($_POST['res'])){
                $result = array_unique($array);
                echo "<pre>";
                print_r($result);
                echo "</pre>";
        }
 
?>

script.js Note: To make this script work make sure you save this file inside the js directory.

$(document).ready(function(){
                        
        displayData();
                
        function displayData(){
                $.ajax({
                        url: "array.php",
                        type: "POST",
                        data: {res: 1},
                        success: function(data){
                                $('#result').html(data);
                        }
                });
        }
        
        $('#delete').on('click', function(){    
                $.ajax({
                        url: "eliminate.php",
                        type: "POST",
                        data: {res: 1},
                        success: function(data){
                                $('#result').html("<center><h4>Eliminating duplicate objects...</h4></center>");
                                $('#delete').attr('disabled', 'disabled');
                                setTimeout(function(){
                                        $('#delete').removeAttr('disabled');
                                        $('#result').html(data);
                                }, 3000);
                        }
                });
        });
