opcache

[hupe13]

WordPress: 7.0-beta1
php 8.5
opcache enabled (file)

The site health checks the existence of opcache in includes/class-wp-site-health.php:

2803: if ( function_exists( 'opcache_get_status' ) )

But opcache_get_status "will not return any information about the file cache". It returns false and site health reports "Opcode cacheDisabled".
See ​https://www.php.net/manual/en/function.opcache-get-status.php

So WordPress incorrectly reports the existence of opcache.

Site Health: Fix OPcache detection when file cache is enabled

opcache_get_status() can return false when OPcache file cache is enabled, even though OPcache is active.
This causes Site Health to incorrectly report the opcode cache as disabled.

Update the detection logic to check whether the Zend OPcache extension is loaded and whether opcache.enable is set, and only rely on opcache_get_status() when it returns valid data.

Fixes false negatives for OPcache file cache setups without affecting existing configurations.
