# getmypid

(PHP 3, PHP 4, PHP 5)

getmypid -- Gets PHP's process ID

## Description

int getmypid ( void )

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

警告
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().
