Nginx/PHP-FPM exec another php script

Question

This works, so exec function is not disabled.

exec('ls');

This doesn't work even thought script.php has 777 chmod.

exec('php script.php');

This doesn't work either.

exec('php -v');

I tried to chmod and chown /var/www/ folder, but it doesn't help. I suppose this is due to the www-data user permissions, looks like it doesn't have access to several bin files.

How can I solve this?

is php in the path? maybe you need to do something like `/usr/bin/php` or wherever it's located — Marko D, Mar 20 '13 at 18:48
why would you use exec to execute a php script within a php file? Why not use `include`? — Green Black, Mar 20 '13 at 18:52

and then get the path and put it in exec() like

exec("/opt/local/bin/php -v");

It works! Thank you :) ... but I can't understand why it works like this? – Andrei Canta Mar 20 '13 at 18:57
it didn't work because the php executable it not added to the path for the user that php-fpm run with or nginx :) this is why you need to use the absolute path – Meabed Mar 20 '13 at 18:58

Is there a way to add the script to www-data user's path? – Andrei Canta Mar 20 '13 at 19:00

try php -f script.php

Im not 100% sure this is correct, but i've always sent the -f flag when passing in a file.

-f Parse and execute . This is already self explanatory ! – Meabed Mar 20 '13 at 19:01
Sorry, I didn't read the part about php -v not working either. I was just answering the `php script.php` part. – Applehat Mar 21 '13 at 21:26
