permission denied on shell_exec

sgalonska

Hello,

I am using the shell_exec() - function to call a php-shellscript from a webpage. By doing this I would like to start a script which might take longer than the web-context allows (30 sec.). Unfortunally I get the error "401 access denied". For testing purposes I set all rights to 777 (yes, it´s a linux server ;-)), but this did not help.
Are there any known bugs or did I do something wrong? Is it generally possible to start a script which might do its job independently from the current request? Maybe anybody can give me a hint?

Thanx
Sebastian

This doesn't make sense. A 401 error is issued by the Web server to indicate you don't have access to the requested resource. In this case the resource should NOT be your shell script, but rather the PHP page that includes the invocation. A permissions problem with the script should generate a complaint from PHP, not from the Web server.

Please post an example showing HOW you are invoking the external program.

I am calling the cli (which is a PHP-script by the way) like this:

$_pathToCli = realpath("../cli/script.php");
$_parameter = " -cat_id=" . $_REQUEST['cat_id'];
$_command = $_pathToCli . " " . $_parameter;
$_result = shell_exec($_command);
echo $_result;
