Questions tagged [include-once]

include_once is a PHP statement that evaluates a file during script execution. This tag should only be used to describe problems involving directly the statement, and not because your code appears to use that statement.

include_once is a PHP statement that includes a specified file during script execution. It is similar to , but with the difference that the code from the file will not be executed again if the file has already been included before. Unlike , if an error occurs when including the file, an E_WARNING is emitted which does not halt script execution.

This tag should only be used if your question describes a problem involving directly the include_once statement, or if it is about include_once usage. Do not use this tag just because your code is using that statement.
