Notice – “Only variables should be passed by reference”

PHP Notice: Only variables should be passed by reference in ../wp-content/plugins/fast-backend/fast-backend.php on line 119

Here is the code:

$isPostTypeOverviewPage = isset($_GET[‘post_type’]) && array_pop( explode( ‘/’, $_SERVER[ ‘PHP_SELF’ ] ) ) !== ‘post-new.php’;

Can it be updated to the following?

// Assign the result of explode() to a variable
$path_parts = explode(‘/’, $_SERVER[‘PHP_SELF’]);

// Pass the variable to array_pop()
$last_part = array_pop($path_parts);

$isPostTypeOverviewPage = isset($_GET[‘post_type’]) && $last_part !== ‘post-new.php’;
