Hi!
Your English is great. Not to slam a few people on this forum, but they even refuse to speak English :-)
Actually, PHP has all the utilities for working with text strings, including regular expressions (simple and posix-extended).
Below are some PHP commands that come to mind. You will need to properly escape strings passed to these functions, etc, because consequences may be dire.
string exec (string command [, string array [, int return_var]])
string system (string command [, int return_var])
Hope this helps,
Stas
