Voorbeeld: example

<?php
$dat = getrusage();
echo $dat["ru_oublock"];       // number of block output operations
echo $dat["ru_inblock"];       // number of block input operations
echo $dat["ru_msgsnd"];        // number of IPC messages sent
echo $dat["ru_msgrcv"];        // number of IPC messages received
echo $dat["ru_maxrss"];        // maximum resident set size
echo $dat["ru_ixrss"];         // integral shared memory size
echo $dat["ru_idrss"];         // integral unshared data size
echo $dat["ru_minflt"];        // number of page reclaims (soft page faults)
echo $dat["ru_majflt"];        // number of page faults (hard page faults)
echo $dat["ru_nsignals"];      // number of signals received
echo $dat["ru_nvcsw"];         // number of voluntary context switches
echo $dat["ru_nivcsw"];        // number of involuntary context switches
echo $dat["ru_nswap"];         // number of swaps
echo $dat["ru_utime.tv_usec"]; // user time used (microseconds)
echo $dat["ru_utime.tv_sec"];  // user time used (seconds)
echo $dat["ru_stime.tv_usec"]; // system time used (microseconds)
echo $dat["ru_stime.tv_sec"];  // system time used (seconds)

Opmerking: > On Windows will only return the following members: getrusage

"ru_stime.tv_sec"``"ru_stime.tv_usec"``"ru_utime.tv_sec"``"ru_utime.tv_usec"``"ru_majflt"``mode``RUSAGE_SELF``"ru_maxrss"``mode``RUSAGE_SELF

If  is called with  
set to  (), then 
resource usage for threads are collected (meaning that internally the function 
is called with ).
