getmypid — Gets PHP's process ID

### Description

int getmypid ( void )

Gets the current PHP process ID.

### Return Values

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

### Notes

Warning

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