Re: [PLUG] calling system from PHP

[Iman Mayes <imayes@verizon.net>]

Thanks for the info. I *suspect* that the program I called was never
executed because by moving it to another location I solved the problem
(probably permissions or something). I think that it was the PHP system
function that returned this code. Maybe PHP is not properly handling the
error codes. The PHP docs say that system() will return any system
errors that are generated on failure and a 0 for success.
