What are the benefits of using a bytecode cache like APC or opcache for PHP?

When PHP scripts are executed, they are first compiled into bytecode, which is then executed by the PHP runtime. This compilation process can be resource-intensive and can slow down the performance of the application. By using a bytecode cache like APC or opcache, the compiled bytecode is stored in memory, reducing the need for recompilation and improving the overall performance of the application. 

// Enable opcache in PHP
if (extension_loaded('Zend OPcache')) {
    ini_set('opcache.enable', 1);
    ini_set('opcache.enable_cli', 1);
    ini_set('opcache.save_comments', 1);
}
