"<br><br>";  EXEC ("Ping-c 3-w 5 $ip", $info); Echo ' Linux info: '.  "<br>";     Print_r ($info);  $ping _time_line = end ($info); Echo ' <br><br>ping_time_line: '. $ping _time_line.     "<br><br>";  $ping _time = explode ("=", $ping _time_line) [1];  $ping _time_min = Explode ("/", $ping _time) [0]/1000.0;  $ping _time_avg = Explode ("/", $ping _time) [1]/1000.0;     $ping _time_max = Explode ("/", $ping _time) [2]/1000.0; Echo $ping _time_min. " " . $ping _time_avg. " " . $ping _time_max.   "<br><br>"; }else//windows{echo ' I am windows '.   "<br><br>";  EXEC ("Ping-c 3-w 5 $ip", $info); echo ' Windows info: '.

function Ping_time ($ip) {  $ping _cmd = "Ping-c 3-w 5". $ip;  EXEC ($ping _cmd, $info);  $ping _time_line = end ($info);     $ping _time = explode ("=", $ping _time_line) [1];  $ping _time_min = Explode ("/", $ping _time) [0]/1000.0;  $ping _time_avg = Explode ("/", $ping _time) [1]/1000.0;  $ping _time_max = Explode ("/", $ping _time) [2]/1000.0;     $result = Array ();  $result [' ping_min '] = $ping _time_min;  $result [' ping_avg '] = $ping _time_avg;  $result [' ping_max '] = $ping _time_max;     Print_r ($result);} Ping_time (' 115.29.237.28 ');

Operation Result:


Array ([ping_min] = 0.025497 [Ping_avg] = 0.025947 [Ping_max] = 0.026753)
