Question

I have the follow code;

<?php
function countryCityFromIP($ipAddr)
{
    $url = "http://api.ipinfodb.com/v3/ip-city/?key=5cfaab6c5af420b7b0f88d289571b990763e37b66761b2f053246f9db07ca913&ip=$ipAddr&format=json";
    $d = file_get_contents($url);
    return json_decode($d , true);
}

if(isset($_REQUEST['submit'])){
   $ip=countryCityFromIP($_REQUEST['ip']);

   //print_r($ip);
   echo $ip['cityName'];
   echo $ip['countryName'];
}
?>

<form method="post">
<input type="text" name="ip" />
<input type="submit" name="submit" value="Find" />
</form>

I need to style "echo $ip['cityName']" here. I tried a lot methods, but I am getting error only. Please help

You can style it by following way

echo "<p style='color:red;'>".$ip['cityName']."</p>";
echo "<p style='color:red;'>".$ip['countryName']."</p>";
