具有exec功能的PHP脚本无法在浏览器中使用，但是如果我使用“ php5 script_name.php”将其运行到终端中，它将可以使用

Question

my problem: I wrote Php web page that use exec function and it doesn't work into browser but it works if I run it into a terminal with "php5 script_name.php"... where is the problem?!!

Thanks a lot!

Answer 1

The problem is that the command line PHP can use a different php.ini file. Try doing phpinfo() and you will see which one each is using.

Answer 2

The most likely problems are that the current working directory is different and/or the PATH environment variable is different and/or the file permissions are different. Probably the current working directory (or permissions). Try putting this before your call to exec() :

chdir($my_directory);

Where $my_directory is the directory from which you're trying to run it in the CLI.

If you're not getting any errors, try putting this at the top of your script:

error_reporting(E_ALL);
ini_set('display_errors', 1);

That might give you a better idea of the problem.
