php获取Linux系统运行时间

php获取Linux系统运行时间代码：

1. <?php
2. function sys_linux() {
3. if (false === ($str = @file("/proc/uptime"))) return false; $str = explode(" ", implode("", $str));
4. $str = trim($str[0]); $min = $str / 60;
5. $hours = $min / 60; $days = floor($hours / 24);
6. $hours = floor($hours - ($days * 24)); $min = floor($min - ($days * 60 * 24) - ($hours * 60));
7. if ($days !== 0) $res['uptime'] = $days."天"; if ($hours !== 0) $res['uptime'] .= $hours."小时";
8. $res['uptime'] .= $min."分钟"; return$res;
9. }
10. $sysInfo = sys_linux(); $uptime = $sysInfo['uptime'];
11. echo$uptime;
12. ?>

效果可以自己测试下，不传图片了。
