getmypid - Gets PHP's process ID

SYNOPSIS
       int getmypid (void  )

DESCRIPTION
	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 con-
	      texts.
