php获取系统从开机到现在已运行时间，在探针里抄来的，只能在linux下有效。
<?php
$sysReShow = (false !== ($sysInfo = sysInfo()))?"show":"none";
function sysInfo()
{
// UPTIME
if (false === ($str = @file("/proc/uptime"))) return false;
$str = explode(" ", implode("", $str));
$str = trim($str[0]);
$min = $str / 60;
$hours = $min / 60;
$days = floor($hours / 24);
$hours = floor($hours - ($days * 24));
$min = floor($min - ($days * 60 * 24) - ($hours * 60));
if ($days !== 0) $res['uptime'] = $days."天";
if ($hours !== 0) $res['uptime'] .= $hours."小时";
$res['uptime'] .= $min."分钟";
// FREETIME
if (false === ($str = @file("/proc/uptime"))) return false;
$str = explode(" ", implode("", $str));
$str = trim($str[1]);
$min = $str / 60;
$hours = $min / 60;
$days = floor($hours / 24);
$hours = floor($hours - ($days * 24));
$min = floor($min - ($days * 60 * 24) - ($hours * 60));
if ($days !== 0) $res['freetime'] = $days."天";
if ($hours !== 0) $res['freetime'] .= $hours."小时";
$res['freetime'] .= $min."分钟";
return $res;
}
?>
<?php
if("show"==$sysReShow){
echo "运行时间:".$sysInfo['uptime']."n";
echo "<br/>n";
echo "空闲时间:".$sysInfo['freetime']."n";
echo "<br/><br/>n";
}
?> |
