通过在WordPress正题文件下的functions.php里,增加自定义函数,可以在页面open的时候显现目前系统内存的使用、统共内存和系统负载等。
本文的函数是扒自雅黑探针的内存获得,其他需要可自行扒取。
显现结果:
自定义函数放入functions.php里
总物理内存:
function memTotal() {
$str = @file("/proc/meminfo");
$str = implode("", $str);
preg_match_all("/MemTotal\s{0,}\:+\s{0,}([\d\.]+).+?MemFree\s{0,}\:+\s{0,}([\d\.]+).+?Cached\s{0,}\:+\s{0,}([\d\.]+).+?SwapTotal\s{0,}\:+\s{0,}([\d\.]+).+?SwapFree\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buf);
preg_match_all("/Buffers\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buffers);
$memTotal = round($buf[1][0]/1024, 2);
return $memTotal;
}
内存使用:
function memUsed() {
$str = @file("/proc/meminfo");
$str = implode("", $str);
preg_match_all("/MemTotal\s{0,}\:+\s{0,}([\d\.]+).+?MemFree\s{0,}\:+\s{0,}([\d\.]+).+?Cached\s{0,}\:+\s{0,}([\d\.]+).+?SwapTotal\s{0,}\:+\s{0,}([\d\.]+).+?SwapFree\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buf);
preg_match_all("/Buffers\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buffers);
$memTotal = round($buf[1][0]/1024, 2);
$memFree = round($buf[2][0]/1024, 2);
$memUsed = $memTotal-$memFree;
return $memUsed;
}
实在内存使用:
function memRealUsed() {
$str = @file("/proc/meminfo");
$str = implode("", $str);
preg_match_all("/MemTotal\s{0,}\:+\s{0,}([\d\.]+).+?MemFree\s{0,}\:+\s{0,}([\d\.]+).+?Cached\s{0,}\:+\s{0,}([\d\.]+).+?SwapTotal\s{0,}\:+\s{0,}([\d\.]+).+?SwapFree\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buf);
preg_match_all("/Buffers\s{0,}\:+\s{0,}([\d\.]+)/s", $str, $buffers);
$memTotal = round($buf[1][0]/1024, 2);
$memFree = round($buf[2][0]/1024, 2);
$memCached = round($buf[3][0]/1024, 2);
$memBuffers = round($buffers[1][0]/1024, 2);
$memRealUsed = $memTotal-$memFree-$memCached-$memBuffers;
return $memRealUsed;
}
系统负载:
function loadAvg() {
$str = @file("/proc/loadavg");
$str = explode(" ", implode("", $str));
$str = array_chunk($str, 4);
$loadAvg = implode(" ", $str[0]);
return $loadAvg;
}
函数援用方法示例:
echo memTotal(); # 统共物理内存
