opcache_invalidate — Invalidates a cached script
opcache_invalidate ( string $filename [, bool $force = false ] ) : bool

filename
The path to the script being invalidated.
force
If set to true, the script will be invalidated regardless of whether invalidation is necessary.
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.
