getmypid — Gets PHP's process ID

说明

int getmypid ( void )

Gets the current PHP process ID.

返回值

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

注释

Warning

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