getrusage
GETRUSAGE(3) 1 GETRUSAGE(3)
getrusage - Gets the current resource usages
SYNOPSIS
array getrusage ([int $who])
DESCRIPTION
This is an interface to getrusage(2). It gets data returned from the system call.
PARAMETERS
o $who
- If $who is 1, getrusage will be called with RUSAGE_CHILDREN.
RETURN VALUES
Returns an associative array containing the data returned from the system call. All entries are accessible by using their documented field
names.
EXAMPLES
Example #1
getrusage(3) 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)
?>
CHANGELOG
+--------+---------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------+
| 7.0.0 | |
| | |
| | This function is now supported on Windows. |
| | |
+--------+---------------------------------------------+
NOTES
Note
On Windows getrusage(3) will only return the following members:
o "ru_stime.tv_sec"
o "ru_stime.tv_usec"
o "ru_utime.tv_sec"
o "ru_utime.tv_usec"
o "ru_majflt" (only if $who is RUSAGE_SELF)
o "ru_maxrss" (only if $who is RUSAGE_SELF)
If getrusage(3) is called with $who set to 1 ( RUSAGE_CHILDREN), then resource usage for threads are collected (meaning that inter-
nally the function is called with RUSAGE_THREAD).
Note
on BeOS 2000, only the following members are returned:
o "ru_stime.tv_sec"
o "ru_stime.tv_usec"
o "ru_utime.tv_sec"
o "ru_utime.tv_usec"
