How can one determine if their GD version is outdated in PHP?

To determine if your GD version is outdated in PHP, you can use the `gd_info()` function to retrieve information about the GD library installed on your server. Look for the value of the key `GD Version` in the array returned by `gd_info()`. If the version number is lower than the minimum required version for your application, you may need to update GD. 

$gdInfo = gd_info();
$gdVersion = $gdInfo['GD Version'];

if(version_compare($gdVersion, '2.0.28', '<')) {
    // GD version is outdated, take necessary actions
    echo "GD version is outdated. Please update GD library.";
} else {
    echo "GD version is up to date.";
}
