Questions tagged [require-once]

The PHP require_once function

The PHP require_once function.

In contrast to require this function only includes the referred file if it has not been included before.

Use this tag only for questions that directly ask about require_once usage. Do not use this tag if your code contains require_once but you have no reason to believe that require_once is directly related to the issue you are asking about.
