PHP Take a phrase value from within the array

Question

People below I have a code that checks the ping on MS of a url or IP but what I need is to take the value of the average of the result that is within the array [10]

Example :

M dia = 74ms

I just wanted the value 74 in a echo.

Below is a test code

<?php
function pingAddress($ip) {
    $pingresult = exec("ping  -n 3 $ip", $outcome, $status);
    if (0 == $status) {
        $status = "alive => ( ".print_r($outcome[10])." )";
    } else {
        $status = "fora";
    }
}
pingAddress("www.google.com");

?>

Answer 1

You can make a runtime calculation using the microtime()

<?php
function ping($host, $port = 80, $timeout = 10) { 
  $tB = microtime(true); // inicia um valor de timestamp 
  $fP = fSockOpen($host, $port, $errno, $errstr, $timeout); // checagem da url pretendida na porta desejada por um tempo determinado
  if (!$fP) { return "down"; } 
  $tA = microtime(true); // inicia um segundo valor de timestamp 
  return round((($tA - $tB) * 1000), 0)." ms"; // calcula o tempo de execução 
}

//Mostrando o ping caso esteja executando se não exibe 'down'
echo ping("www.google.com", 80, 10);
