简单的php获取linux服务器状态的代码，不多说-直接上函数：
复制代码 代码如下:
function get_used_status(){
$fp = popen(‘top -b -n 2 | grep -E “^(Cpu|Mem|Tasks)”‘,”r”);//获取某一时刻系统cpu和内存使用情况
$rs = “”;
while(!feof($fp)){
$rs .= fread($fp,1024);
}
pclose($fp);
$sys_info = explode(“/n”,$rs);
$tast_info = explode(“,”,$sys_info[3]);//进程 数组
$cpu_info = explode(“,”,$sys_info[4]); //CPU占有量 数组
$mem_info = explode(“,”,$sys_info[5]); //内存占有量 数组
//正在运行的进程数
$tast_running = trim(trim($tast_info[1],’running’));
//CPU占有量
$cpu_usage = trim(trim($cpu_info[0],’Cpu(s): ‘),’%us’); //百分比
//内存占有量
$mem_total = trim(trim($mem_info[0],’Mem: ‘),’k total’);
$mem_used = trim($mem_info[1],’k used’);
$mem_usage = round(100*intval($mem_used)/intval($mem_total),2); //百分比
