Enable PHP OPcache: Faster PHP Without Changing Any Code

What OPcache does

Through the MultiPHP INI Editor, two minutes flat:

1. Open the editor — cPanel > MultiPHP INI Editor, pick the domain
2. Enable the switch — opcache.enable=1
3. Size the cache — opcache.memory_consumption=128 (MB) suits most WordPress sites
4. Save — PHP-FPM reloads automatically
5. Verify — phpinfo() shows 'Zend OPcache' enabled; reload speed drops immediately

OPcache keeps compiled PHP bytecode in memory, skipping recompilation per request — the cheapest real speedup available. Two gotchas: validate_timestamps off means code changes need a reload (the 'changes not showing' classic), and LiteSpeed+LSCache handles the page layer while OPcache handles PHP. Our cPanel hosting plans pre-tune both, and the PHP version guide pairs the upgrade.

Checking if it is running

Checking if it is running. Do the change this heading names on one site first, then check it in a private browser window or in the mail client, depending on the topic. Change one setting at a time, and undo it if the result is wrong before you try the next.

Enabling in cPanel step by step

Two practical notes on php.ini directives (opcache.enable, memory_consumption): it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.

The 'changes not showing' fix

How this plays out with max_accelerated_files: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.

Verifying with phpinfo and speed tests

Create a temporary file that only calls phpinfo(), open it in the browser, and read the PHP version, memory_limit and loaded extensions. Delete the file as soon as you have checked it. A blank page usually means the file is outside the document root, or PHP is not enabled for that site.
