Disable OPCache temporarily

Question

I recently moved to PHP 5.4 and installed OPCache, it's very powerful! How can I temporarily disable the cache? I tried : ``` ini_set('opcache.enable', 0); ``` But it has no effect. Thanks

Accepted Answer

Once your script runs, it's too late to not cache the file. You need to set it outside PHP:

If PHP runs as Apache module, use an `.htaccess` file:

```
php_flag opcache.enable Off
```

If PHP runs as CGI/FastCGI, use a `.user.ini` file:

```
opcache.enable=0
```

In all cases, you can also use good old system-wide `php.ini` if you have access to it.
