How can the configuration option register_long_arrays impact PHP scripts?

The configuration option register_long_arrays impacts PHP scripts by determining whether the deprecated long predefined variable arrays like $HTTP_GET_VARS, $HTTP_POST_VARS, etc. are registered and accessible. It is recommended to set this option to Off as these long arrays have been removed in PHP 5.4 and later versions. To fix this issue, you should update your scripts to use the superglobals like $_GET, $_POST, etc. instead.

// Set register_long_arrays to Off in php.ini configuration file
// Update your PHP scripts to use superglobals instead of long arrays

// Example of accessing GET data using superglobal $_GET
$value = $_GET['key'];
