Sanitizing PHP input to ping program

Question

I would like to interface a php page to the linux command line program ping.

I realize that there are sanitation issues. Is there a builtin library or function that can take care of everything, or will I have to rely on regex parsers?

Answer 1

Do you mean escapeshellcmd and escapeshellarg?

Answer 2

do you mean to sanitize variable http://php.net/filter_var ?
