PHP: The Array Element Doesn’t Exist

PHP: The Array Element Doesn’t Exist – Suppress the Warnings

What’s the problem?

If you code PHP from couple of hours you are probably familiar with the following problem:

<?php
 
	error_reporting(E_ALL);
 
	$arr = array();
 
	echo $arr[3];
 
?>

The first and most common solution is just by adding the isset() statement and the code will look like that:

<?php
 
	error_reporting(E_ALL);
 
	$arr = array();
 
        if (isset($arr[3]))
	        echo $arr[3];
 
?>

However do you know there’s is another simple and elegant solution? Simply add the @ sign to suppress the element existence

<?php
 
	error_reporting(E_ALL);
 
	$arr = array();
 
	echo @$arr[3];
 
?>
