[kenxx]

Hello!

• Type: bug fix
• Link to issue:

There's no issues for this bug. Turns out this Config Scanner can not load php native properly, so I went to the source code. There is a method that the comment saids return a null or PhConfig value, but Config is given, then I correct it.

please check this pr, have a nice day :)
