In what situations would upgrading to a higher-tier hosting package be necessary for PHP functionality, and what factors should be considered before making that decision?

Upgrading to a higher-tier hosting package may be necessary for PHP functionality when you require more server resources such as CPU, memory, or storage to handle increased traffic or complex PHP scripts. Factors to consider before making this decision include the current and projected traffic levels, the complexity of your PHP scripts, and the performance requirements of your website. 

<?php
// PHP code snippet implementing the fix
// Check server resources and upgrade if necessary
if (function_exists('memory_get_usage')) {
    $memory_limit = ini_get('memory_limit');
    $memory_usage = memory_get_usage();

    if ($memory_usage > $memory_limit) {
        // Upgrade to a higher-tier hosting package
        echo "Upgrade hosting package for better PHP functionality.";
    } else {
        echo "No need to upgrade hosting package.";
    }
}
?>
