ParamsReturnRelatedSource
Parses a PHP file for messages marked as translatable. Recognized as message marking are `$t()` and `$tn()` which are implemented in the `View` class. This is a rather simple and stupid parser but also fast and easy to grasp. It doesn't actively attempt to detect and work around syntax errors in marker functions.

Parameters

  • string $file Absolute path to a PHP file.

Returns

array
