exec() command from web server in php

Is there anyway to us开发者_开发问答e atrm command to remove queue job from PHP web application? I wrote a shell script to remove the queue job but it doesn't work well.

#! /bin/sh

export PATH=/usr/local/bin:$PATH

echo atrm 3700 2>&1

You can try doing:

echo exec('export PATH=/usr/local/bin:$PATH ; atrm 3700 2>&1');

Try atrm 3700 2 > &1 without echo

You can use shell_exec or exec PHP function :

$output=shell_exec($commandstring);
print_r($output);

or

 exec($commandstring,$output,$returnval);
 print_r($output);
 print_r($returnval);
