# 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.

See also getmygid(), getmyuid(), get_current_user(), getmyinode(), and getlastmod().
