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
