Enabling PHP opcode caching

Opcode caching improves PHP performance by storing precompiled script bytecode in memory. This allows PHP to serve pages faster without recompiling scripts on every request. On ruachost.com, you can enable opcode caching through cPanel.

About APC and OPcache

• APC (Alternative PHP Cache)

  • Works with PHP 5.4 and earlier.

  • Requires installation as a separate extension.

• OPcache

  • Built into PHP 5.5 and later.

  • Drop‑in replacement for APC.

  • No separate installation required.

Steps to Enable Opcode Caching

Step 1: Log in to cPanel

• Access your hosting account at ruachost.com.

• Open cPanel from your dashboard.

Step 2: Select PHP Version

1. In cPanel, go to Software → Select PHP Version.

2. If you don’t see this option, your server may not support it.

Step 3: Enable the Extension

• For PHP 5.4 or older: check the box for apc.

• For PHP 5.5 or newer: check the box for opcache.

• Click Save to apply changes.

Step 4: Verify

• Create a file named info.php in your site’s root directory:

  <?php phpinfo(); ?>
  

• Visit http://yourdomain.com/info.php.

• Look for the APC or OPcache section to confirm it is enabled.

• Delete the file afterward for security.
