Get the priority of any process

int pcntl_getpriority ([ int $pid = getmypid() [, int $process_identifier = PRIO_PROCESS ]] )

pcntl_getpriority() gets the priority of pid. Because priority levels can differ between system types and kernel versions, please see your system's getpriority(2) man page for specific details.

process_identifier

One of PRIO_PGRP, PRIO_USER or PRIO_PROCESS.
