In this tutorial, we will create a Sorting Array Key using PHP. This code will sort array value when the user selects the proper order in the table. The system uses the PHP POST method that calls specific functions to sort the array value using array_multisort by setting the parameter with an array index position and array order type. This is a user-friendly kind of program feel free to modify it.
We will be using PHP as a scripting language and interpreter, which is mainly used on any web server, including xamp, wamp, etc. It is being used to any popular websites, and it has a modern technology that can easily be used by the next generation.
Getting Started:
First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the 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 structures, 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 - Sorting Array Key</h3>
<hr style="border-top:1px dotted #ccc;"/>
<form method="POST" action="">
<div class="form-inline">
<select name="key" required="required" class="form-control">
<option value="sort_asc">Ascending</option>
<option value="sort_desc">Descending</option>
</select>
<button name="sort" class="btn btn-primary">Sort</button>
<div>
</form>
<br />
<div class="col-md-6">
<table class="table table-bordered">
<thead class="alert-info">
<tr>
<th>Member Name</th>
<th>Address</th>
</tr>
</thead>
<tbody>
<?php include 'sort.php'?>
</tbody>
</table>
</div>
</div>
</body>
</html>
Creating the Main Function
This code contains the main function of the application. This code will sort array value 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 sort.php
<?php
$members = array(
array("name" => "Tony Stark", "address" => "Japan"),
array("name" => "Peter Piper", "address" => "New York"),
array("name" => "Carl Roger", "address" => "London"),
array("name" => "Isko Sky", "address" => "England"),
array("name" => "Zia Adantos", "address" => "Egypt")
);
if(ISSET($_POST['sort'])){
$sortKey = array();
$sort = $_POST['key'];
foreach($members as $member){
foreach($member as $key=>$value){
if(!isset($sortKey[$key])){
$sortKey[$key] = array();
}
$sortKey[$key][] = $value;
}
}
$sortby = "name";
if($sort == "sort_asc"){
array_multisort($sortKey[$sortby],SORT_ASC,$members);
}else if($sort == "sort_desc"){
array_multisort($sortKey[$sortby],SORT_DESC,$members);
}
foreach($members as $key => $values){
?>
<tr>
<td><?php echo $values['name']?></td>
<td><?php echo $values['address']?></td>
</tr>
<?php
}
}else{
foreach($members as $key => $values){
?>
<tr>
<td><?php echo $values['name']?></td>
<td><?php echo $values['address']?></td>
</tr>
<?php
}
}
?>
