backtick.deprecated

Code example

<?php declare(strict_types = 1);

$output = `ls -la`;

Why is it reported?

The backtick operator (`) is deprecated in PHP 8.5. It is equivalent to shell_exec(), but its syntax makes it easy to confuse with single quotes and harder to spot in code. PHP 8.5 deprecates this operator in favour of the explicit shell_exec() function call.

How to fix it

Replace the backtick operator with a shell_exec() call:

 <?php declare(strict_types = 1);

-$output = `ls -la`;
+$output = shell_exec('ls -la');
