php获取Linux系统运行时间

php获取Linux系统运行时间代码：

1. <?php
3. function sys_linux()
4. {
5. if (false === ($str = @file(“/proc/uptime”))) return false;
6. $str = explode(” “, implode(“”, $str));
7. $str = trim($str[0]);
8. $min = $str / 60;
9. $hours = $min / 60;
10. $days = floor($hours / 24);
11. $hours = floor($hours – ($days * 24));
12. $min = floor($min – ($days * 60 * 24) – ($hours * 60));
13. if ($days !== 0) $res[‘uptime’] = $days.“天”;
14. if ($hours !== 0) $res[‘uptime’] .= $hours.“小时”;
15. $res[‘uptime’] .= $min.“分钟”;
16. return$res;
17. }
19. $sysInfo = sys_linux();
20. $uptime = $sysInfo[‘uptime’];
22. echo$uptime;
24. ?>

效果可以自己测试下，不传图片了。
