In what ways can the PHP version running on a web hosting provider affect the performance and functionality of PHP scripts?

The PHP version running on a web hosting provider can affect the performance and functionality of PHP scripts by potentially causing compatibility issues with newer PHP features or deprecated functions. To ensure optimal performance and functionality, it is recommended to use the latest stable PHP version supported by the hosting provider. 

// Example of checking PHP version and implementing a workaround for compatibility issues
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    // Workaround for older PHP versions
} else {
    // Use newer PHP features
}
