How to Make a PHP Loop

Using a loop, you can execute a certain piece of code a specified number of times. PHP has three loops: while, for and foreach. Let's see how to make them.

The while Loop

The while loop will execute as long as the expression passed to it as a parameter is true. See the example:

<?php
	$i = 1;
	while ($i <= 5) {
		echo $i;
		$i++;
	}
?>

Code execution result:

12345

The for Loop

The for loop is similar to while, but more compact. See the example:

<?php
	for ($i = 1; $i <= 5; $i++) {
		echo $i;
	}
?>

Code execution result:

12345

The foreach Loop

The foreach loop is used to iterate through all elements of an array. See the example:

<?php
	$arr = [1, 2, 3, 4, 5];
	
	foreach ($arr as $elem) {
		echo $elem;
	}
?>

Code execution result:

12345
