How does the PHP version affect the functionality of certain built-in functions like htmlentities?

The PHP version can affect the functionality of certain built-in functions like htmlentities because newer PHP versions may introduce changes or improvements to these functions. To ensure consistent behavior across different PHP versions, it's recommended to check the PHP documentation for each function to understand any version-specific differences and adjust your code accordingly. 

// Example of using htmlentities with version-specific checks
if (version_compare(PHP_VERSION, '7.4.0') >= 0) {
    $encodedString = htmlentities($inputString, ENT_QUOTES | ENT_HTML5, 'UTF-8');
} else {
    $encodedString = htmlentities($inputString, ENT_QUOTES, 'UTF-8');
}
