How does the use of Opcode Caches impact the parsing and interpretation process of PHP scripts?

Opcode caches can significantly improve the performance of PHP scripts by storing precompiled bytecode in memory, reducing the need for parsing and interpretation of scripts on each request. This can lead to faster execution times and improved overall server performance. 

// Example of implementing Opcode Caches using OPcache extension

// Enable OPcache
if (!extension_loaded('Zend OPcache')) {
    die('OPcache extension is not loaded');
}

// Check if OPcache is enabled
if (!ini_get('opcache.enable')) {
    ini_set('opcache.enable', 1);
}

// Check if OPcache is already caching files
if (!ini_get('opcache.enable_cli')) {
    ini_set('opcache.enable_cli', 1);
}
