Linking 2 arrays after successful ping in PHP

[Jimmy85]

Hi,

Basically I have written this PHP script to ping address on my network and then I would like to add the name that defines that IP after my image if successful or not.

I am struggling on the name part can anyone assist?

My code is below:

<?php
$systems = array("192.168.9.254","192.168.9.205","192.168.9.200","192.168.9.201","192.168.9.1","192.168.9.2","192.168.9.3","192.168.9.4","192.168.9.7","192.168.9.13");
$Sysname = array("Item1","Item2","Item3","Item4","Item5","Item6","Item7","Item8","Item9");
$good = "Received = 1";
$successValue;
//echo "<h1>Site Status  ".date("h:i:s")."</h1>";
echo "<br><br>";
foreach ($systems as $ip) {
    unset($result);
    $successValue = "DOWN";
    exec("ping -n 1 $ip", $result);
    foreach($result as $line) {
        if (strpos($line,$good) == TRUE){
            $successValue = "UP";
        }
    }
    echo "IP Address: ".$ip." ";
    If ($successValue == "UP") {
         echo "System is ".$successValue. "&nbsp;"."<img src='/Images/GTick.jpg'>"."&nbsp;";

    }else{
            echo "System is ".$successValue. "&nbsp;"."<img src='/Images/RTick.jpg'>"."&nbsp;";
    }
echo "<br><br>";
//var_dump($result);
}
?>

Cheers James

I would switch to a multidimensional associative array for your data. For example, you could have something like this

<?php
$systems = array(
	array('ip'=>'192.168.9.254', 'name'=>'Item1'),
	array('ip'=>'192.168.9.205', 'name'=>'Item2'),
	
	//...remaining systems
	
);
?>

 

That way all your data is in the same place. Then your loop could use the values like this:

<?php
foreach ($systems as $currSystem) {
	echo $currSystem['ip'];
	echo $currSystem['name'];
}
?>

I was going to suggest combining the arrays

$systems = array_combine($systems, $Sysname);

then you could

foreach ($systems as $ip => $name) {
    // ping
}

However, to that that you would need the same number of names as there are IPs. It would give

Array
(
    [192.168.9.254] => Item1
    [192.168.9.205] => Item2
    [192.168.9.200] => Item3
    [192.168.9.201] => Item4
    [192.168.9.1] => Item5
    [192.168.9.2] => Item6
    [192.168.9.3] => Item7
    [192.168.9.4] => Item8
    [192.168.9.7] => Item9
    [192.168.9.13] => Item10
)
