How PHP Gets the ping time

This article mainly introduces the PHP to get ping time implementation of the relevant information, hope that through this article can help everyone, so that we can achieve such a function, the need for friends to refer to the next

PHP can use the EXEC function to execute shell commands to get ping time.

code example:

Echo ' Php_int_max: '. Php_int_max. "<br><br>";    $ip = ' 115.29.237.28 '; IP address if (path_separator== ': ')//linux{echo ' I am Linux '.     "<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", $info); echo ' Windows info: '.  "<br>";     Print_r ($info);  $info _time = end ($info); Echo ' <br><br>info_time: '. $info _time. "<br><br>";}

Operation Result:

php_int_max:9223372036854775807

Get ping time encapsulated into function

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)
