file_put_contents() doesn't throw exceptions. As the note on the exception 
documentation says: "Internal PHP functions mainly use Error reporting, only 
modern Object oriented extensions use exceptions."

If you look at the documentation for its return value 
(http://php.net/file_put_contents), you'll see that false is returned on 

In this case, a warning makes more sense than throwing an exception anyway. A 
warning can be ignored, either by changing the error_reporting level or using 
the error control operator, whereas an exception must be dealt with or 
execution halts.
