PHP not reading psexec output

问题

The problem is simple. Running a php file in browser vs command line produces very different results and I can't for the life of me figure out why. Any php/psexec experts out there run into this before?

<?php

echo '<pre>';
$output = shell_exec("psexec -accepteula \\\mypcname -u mypcname\\accountname -p xxxxxxx ipconfig /all 2>&1");
var_dump($output);
echo '</pre>';

Produces this output in a browser window...

Starting PSEXESVC service on admin-pc...


Connecting with PsExec service on admin-pc...


Starting ipconfig on admin-pc...


ipconfig exited on admin-pc with error code 0.

Instead of this, which is the output I get when running the same php file via command line.
