Beware that only existing files can be invalidated.
Instead of removing a file from opcache that you have delete, you need to call opcache_invalidate before deleting it.

opcache_invalidate — Invalidates a cached script
Descrierea
opcache_invalidate
( string
$filename
, bool $force = false
) : bool
This function invalidates a particular script from the opcode cache. If
force is unset or false, the script will only be
invalidated if the modification time of the script is newer than the cached
opcodes.
Parametri
-
filename -
The path to the script being invalidated.
-
force -
If set to
true, the script will be invalidated regardless of whether invalidation is necessary.
Valorile întoarse
Returns true if the opcode cache for filename was
invalidated or if there was nothing to invalidate, or false if the opcode
cache is disabled.

opcache_invalidate tries to acquire SHM lock. When the lock can not be acquired opcache_invalidate will return FALSE. During multiple concurrent opcache_invalidate calls with higher probability, the function will return FALSE.

Note that invalidation doesn't actually evict anything from the cache, it just forces a recompile. You can verify this by calling opcache_get_status() and seeing that the invalidated script is not actually removed from "scripts". This means it cannot be used as a more graceful alternative to opcache_reset() when the cache is full ("cache_full":true in status). The cache will eventually fill up and refuse to cache new requests if you do atomic deployment of PHP code by changing the web server's document root. It appears opcache_reset() is the only way to prevent this, but opcache_reset() can disable the cache for any amount of time while attempting to restart, causing load spikes.
