PHP Array Iteration

To iterate over an array in PHP, the foreach loop is used.

Let's say we have an array:

<?php
	$arr = [1, 2, 3, 4, 5];
?>

Let's use the foreach loop to display all its elements on the screen:

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

Code execution result:

12345
