This shouldn't work at all. By passing 'w' to fopen, you are saying
"Please truncate this file to zero length." The fact that
file_get_contents can still read it is an accident.
Your best bet is probably to move the "fopen" after the
"file_get_contents". Or, perhaps, use "r+" instead of "w" and use fread to
get the contents.
