Run comand line php over the web using php

I have a command line php (not mine, from cartocamp) which i can run on command line by issuing the following commands:
cd C:\ms4w\apps\cartoweb3

php cw3setup.php --clean

php cw3setup.php --install --config-from-file path_conf_file/conf_file.properties
What it does is clean the folder system and setup a map application again.
I wrote php code that creates this map application, creates the config_file and a batch file. I then wrote the following php command to run this application but it doesnt work and i have no idea why.

$run = pclose(popen('start /b '.$batchbase.'\\'.$dir.'.bat', 'r'));

PHP:

thank you

 

Hi,

You might want to try the PHP Backtick Operator or The System and Exec commands.
