getmypid

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

getmypid -- Get PHP's process ID.

Description

int getmypid (void)

Returns the current PHP process ID, or FALSE on error.

Warning

Process IDs are not unique, thus they are a weak entropy source. We recommend against relying on pids in security-dependent contexts.
