How can outdated PHP versions affect the ability to access variables passed between frames?

Outdated PHP versions may lack support for certain features or security updates that are necessary for passing variables between frames. To solve this issue, it is recommended to update PHP to a newer version that includes the necessary functionality and security patches. 

<?php
// Check if PHP version is at least 7.0
if (version_compare(PHP_VERSION, '7.0.0') >= 0) {
    // Code to pass variables between frames
    // Example: $variable = $_POST['variable'];
} else {
    echo "Please update PHP to a version that supports passing variables between frames.";
}
?>
