How do I implode the output of below code into divs instead of echo "On" or "Off"?
I also want the divs to have background color of green if node is ON, and background of red if node is OFF:
<html>
<body>
<?php
for ($ipa=65; $ipa <= 72; $ipa++){
$ip = "10.32.12.".$ipa;
$ping_output=array();
exec ("ping -n 1 -w 1 $ip 2>&1", $ping_output, $return_val);
//echo $ip." -> ".$return_val."<br/>".implode('<br/>',$ping_output).'<br/>';
if(stripos($ping_output[2],"TTL")!==false) {
echo $ip." is On <br/>";
} else if(stripos($ping_output[2],"unreachable")!==false){
echo $ip." is unreachable <br/>";
} else if(stripos($ping_output[2],"request")!==false){
echo $ip." is Off <br/>";
}
}
?>
</body>
</html>
here is something that I did, hope it helps you:
back-end, q3.php
<?php
$result = array();
for ($ipa=65, $i = 1; $ipa <= 72; $ipa++, $i++){
$ip = "10.32.12.".$ipa;
$ping_output=array();
exec ("ping -n 1 -w 1 $ip 2>&1", $ping_output, $return_val);
//echo $ip." -> ".$return_val."<br/>".implode('<br/>',$ping_output).'<br/>';
if(stripos($ping_output[2],"TTL")!==false) {
// echo $ip." is On <br/>";
$result["enode".$i] = "on";
} else if(stripos($ping_output[2],"unreachable")!==false){
// echo $ip." is unreachable <br/>";
$result["enode".$i] = "unreachable";
} else if(stripos($ping_output[2],"request")!==false){
// echo $ip." is Off <br/>";
$result["enode".$i] = "off";
}
}
echo json_encode($result);
?>
front-end, q3h.html
<!DOCTYPE html>

</div>
<script>
$(document).ready(function () {
$("button").click(function () {
$.ajax({
url: "q3.php",
dataType: 'json',
success: function (result) {
alert(result);
for (key in result) {
id = "#"+key;
if (result[key] == "on") {
$(id).css("background-color", "green");
}
if (result[key] == "unreachable") {
$(id).css("background-color", "yellow");
}
if (result[key] == "off") {
$(id).css("background-color", "red");
}
}
}});
});
});

so basically, this is what you should do, don't be shy and tell me if this works for you. :)
