How can PHP version compatibility affect the implementation of a script to modify RDF content?

PHP version compatibility can affect the implementation of a script to modify RDF content if the script uses functions or features that are only available in certain PHP versions. To solve this issue, it is important to check the PHP version before running the script and handle any version-specific code accordingly. This can be done using PHP's built-in functions like `phpversion()` or by using version comparison operators.

// Check PHP version before running the script
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    die('This script requires PHP 7.0 or higher');
}

// Code to modify RDF content goes here
