Hi,

Do you know of any PHP secret functions, tips or advanced functions like error_reporting(15); , it`s not very secret, but was not in my Beginning with PHP book... :D

hmmm.....

system() is pretty nifty, it can be used to execute shell commands via the apache nobody user. I have yet to test it out, but I believe if the server is on windows, that you can reboot the machine.

I think i'll try that now...

Well assuming safe_mode isn't enabled you can... or the host hasn't blocked system() in php.ini

Not if your servers are setup right.

sleep(); - good for security
