So i have this code that whenever an IP is ping able or up it'll choose the green line to appear on my screen and in reverse the red line. So what I am trying to do instead if the Round Trip Time of that IP is < 200 then it's green and when it's > 250 it's red . How can i do that? Anyone help me. Thank you.
<?php
$page = $_SERVER['PHP_SELF'];
$sec = 5;
function pingAddress($TEST) {
$pingresult = exec("ping -c 1 $TEST", $output, $result);
if ($result == 0) {
echo "Ping successful!";
echo "<pre>Your ping: $TEST</pre>";
echo "<hr color = \"green\" width = 40%> GOOD";
} else {
echo "Ping unsuccessful!";
echo "<pre>Your ping: $TEST</pre>";
echo "<hr color = \"red\" width = 40%> BAD";
}
}
pingAddress("66.147.244.228");
?>

The exec function is ok to use, but you should parse the contents of the output argument, after declaring it first as an array. Even if you added -c 1 to only issue one ping, this is the recommended way of using exec.
define('RETRIES', 1);
define('PING_PATH', '/usr/bin/ping');
function pingAddress($IP)
{
$output = array();
exec(PING_PATH . " -c " . RETRIES . " $IP", $output);
// generic way, even for one line. You can also do -c 4,
// and preg_match will pick the first meaningful result.
$output_string = implode("; ", $output);
/// adapt the regular expression to the actual format of your implementation of ping
if (preg_match('/ time=\s+(\d+)ms/', $output_string, $bits)) {
$rt_time = (int)$bits[1];
if ($rt_time < 200) {
// green business
}
else if ($rt_time > 250) {
// red business
}
else {
// default handler business (or not...)
}
}
else {
echo "Hum, I didn't manage to parse the output of the ping command.", PHP_EOL;
}
}
