Are there any specific best practices to follow when caching PHP files to optimize performance?

Caching PHP files can greatly improve performance by reducing the need to recompile and execute the same code repeatedly. One common best practice is to use opcode caching, which stores compiled PHP scripts in memory to avoid the overhead of parsing and compiling the code on each request. 

// Enable opcode caching in PHP
// Example using OPcache extension
if (!extension_loaded('Zend OPcache')) {
    die('OPcache not available');
}

// Check if OPcache is enabled
if (ini_get('opcache.enable')) {
    echo 'OPcache is enabled';
} else {
    echo 'OPcache is not enabled';
}
