How can one optimize PHP code to prevent issues related to outdated PHP versions on web hosting providers?

To optimize PHP code and prevent issues related to outdated PHP versions on web hosting providers, it is important to use PHP functions and syntax that are compatible with a wide range of PHP versions. This includes avoiding deprecated functions and features that may not be supported in older PHP versions. Additionally, regularly updating your PHP codebase and using version control systems can help ensure compatibility with newer PHP versions. 

// Example of using a ternary operator instead of the deprecated split() function
$words = "Hello,World,PHP";
$separator = ",";
$wordArray = (version_compare(PHP_VERSION, '8.0.0') >= 0) ? explode($separator, $words) : split($separator, $words);
