file_put_contents($file, $email);

when this line is uncommented I get an warning in the gmail


PHP Warning:  file_put_contents(2013_01_13_20_42_01_ray_paseur_AT_gmail_com.txt): failed to open stream: Permission denied in /folder/pipe.php

even though the file is written


I want to suppress the writing of warning because gmail sends me a failure email back

you can supress the message by adding an @ as a prefix of your function

@file_put_contents($file, $email);

I'm very surprised that the file is written if you are getting that message. Are you absolutely 100% certain that the file is being written?

@
suppresses the warning and the gmail error email


the file is not being written: when I use a pipe (via email)
but gets written when I run file in browser

you are both correct

the pipe required me to write the entire file path

and

@
hides the warning (which does not exist now)

thanks
