Getting server status code using php in linux _ PHP Tutorial

In simple linux, php gets the server status code. Simple linux php get Server status code, not to mention-directly on the function: functionget_used_status () {$ fppopen (top-b-n2 | grep-E ^ (Cpu | Mem | Tasks ), r); get a simple php code in linux to get the server status:

Function get_used_status (){
$ Fp = popen ('top-B-n 2 | grep-E "^ (Cpu | Mem | Tasks)" ', "r "); // Obtain the cpu and memory usage of the system at a specific time point
$ Rs = "";
While (! Feof ($ fp )){
$ Rs. = fread ($ fp, 1024 );
}
Pclose ($ fp );
$ Sys_info = explode ("\ n", $ rs );

$ Tast_info = explode (",", $ sys_info [3]); // process array
$ Cpu_info = explode (",", $ sys_info [4]); // array of CPU usage
$ Mem_info = explode (",", $ sys_info [5]); // array of memory shares

// Number of running processes
$ Tast_running = trim ($ tast_info [1], 'running '));
// CPU usage

// Memory usage
$ Mem_total = 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); // percentage

Return array ('CPU _ usage' => $ cpu_usage, 'mem _ usage' => $ mem_usage, 'HD _ avail '=> $ hd_avail, 'HD _ usage' => $ hd_usage, 'tast _ running '=> $ tast_running, 'Detection _ time' => $ detection_time );
