This is an interface to getrusage(2). It returns an associative
array containing the data returned from the system call. If who
is 1, getrusage will be called with RUSAGE_CHILDREN.
All entries are accessible by using their documented field names.
Пример 1. getrusage() example
<?php $dat = getrusage(); echo $dat["ru_nswap"]; // number of swaps echo $dat["ru_majflt"]; // number of page faults echo $dat["ru_utime.tv_sec"]; // user time used (seconds) echo $dat["ru_utime.tv_usec"]; // user time used (microseconds) ?>
See your system's man page on getrusage(2) for more details.
