PHP shell_exec cannot find environment variable

Question

I have added this line PATH DEFAULT=${PATH}:~/bin/ to the ~/.pam_environment This allows me to call ffmpeg from command line without path which is obviously in ~/bin/ dir so everything works fine as long as im ussing command line.

But if try to run the exact same command from php all i get is sh: ffmpeg: not found And the code is

shell_exec("ffmpeg 2>&1");

So from my very little experiance with linux (in this case Ubuntu to be specific) i guess apache has no access to pam_environment or ~/bin

What can i do to make this work?

iirc the ~ is your home dir. So that would be a different directory for apache, wouldn't it? Try setting the full path. — winkbrace

look at the output of phpinfo(), it has a section with all environment variables it sees. then look at your webserver configuration, maybe it's sanitizing the environment, or maybe the init script which starts your webserver does it.

and is the account the webserver is running under using PAM at all?
