You can visit the PHP man page for curl() there are plenty of examples.

You can also see my recent blog post where I implement curl in an example bit of code to check for a file in a failover scenario:

So I take it I somehow have to replace get_file_contents with something like this:
Code:
 // create curl resource
        $ch = curl_init();

        // set url
        curl_setopt($ch, CURLOPT_URL, "$ip");

        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        // $output contains the output string
        $output = curl_exec($ch);

        // close curl resource to free up system resources
        curl_close($ch);

Forgive me for I am trying, LOL Smilie

No, you need to send a URL to curl() as a argument, not an IP address.

From my example in the blog post:

Code:
define('HEARTBEAT', 'myCDNexample.com/heartbeat.html');
curl_setopt($ch, CURLOPT_URL, HEARTBEAT);

This works:
Code:
<?php

function getWeather() {
    
   if (!empty($_SERVER['HTTP_CLIENT_IP']))
    {
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
    {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
        $ip = $_SERVER['REMOTE_ADDR'];
    }
    $url = "http://api.hostip.info/get_html.php?ip=$ip";
    define('LOCALE', $url);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, LOCALE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_FAILONERROR, TRUE);
    $geo = curl_exec($ch);
    curl_close($ch);
    if( preg_match('/City: (.*)\nIP:/', $geo, $matches) ){
        $results = $matches[1];
    }else{
        $results = 'getLocation failure';

    }

$location = urlencode($results);
$getAddress = "http://www.google.com/ig/api?weather=$location";
$xml_str = file_get_contents($getAddress,0);
$xml = new SimplexmlElement($xml_str);
$count = 0;
echo '<div id="weather">';
foreach($xml->weather as $item) {

foreach($item->forecast_information as $new) {
            echo $new->city['data'];
            }

        foreach($item->current_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
	    echo $new->condition['data'];
            echo $new->temp_f['data'];
            echo $new->temp_c['data'];
            echo $new->humidity['data'];
            echo $new->wind_condition['data'];
            echo '</div>';
            }

        foreach($item->forecast_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
            echo $new->day_of_week['data'];
            echo $new->condition['data'];
            echo $new->low['data'];
            echo $new->high['data'];
            echo '</div>';
            }

    }

echo '</div>';
}

getWeather();

?>

Have I missed anything?

Yes,

First of all, PHP define() is used for constants, not variables, so you can't use a variable to define a constant Smilie

Second, you are still using get_file_content() in another part of the script to get the contents of a URL. Change that to another curl() call. Maybe you can create a small function?

Remember, define() is only for constants. In my script, my URL is a constant, yours is a variable so you should not use define(). My code is example code and my example uses a constant, but your code uses a variable. (Hint: pass $url to curl(), not LOCALE).

---------- Post updated at 20:50 ---------- Previous update was at 20:40 ----------

For example.....

Code:
define('HOSTIP_QUERY', 'http://api.hostip.info/get_html.php?ip=');

// blah blah

$url = HOSTIP_QUERY.$ip;
curl_setopt($ch, CURLOPT_URL, $url);

define() statements (for constants) should be at the top of the script, or in a config file you read when the script start Smilie

This works:

        $ip = $_SERVER['HTTP_CLIENT_IP'];

    {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
        $ip = $_SERVER['REMOTE_ADDR'];
    }

    $url0 = QUERY_0.$ip;
    $ch0 = curl_init();
    curl_setopt($ch0, CURLOPT_URL, $url0);
    curl_setopt($ch0, CURLOPT_HEADER, 0);
    curl_setopt($ch0, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch0, CURLOPT_FAILONERROR, TRUE);
    $geo = curl_exec($ch0);
    curl_close($ch0);
    if( preg_match('/City: (.*)\nIP:/', $geo, $matches) ){
        $results = $matches[1];
    }else{
        $results = 'getLocation failure';

    }

    $location = urlencode($results);
    $url1 = QUERY_1.$location;
    $ch1 = curl_init();
    curl_setopt($ch1, CURLOPT_URL, $url1);
    curl_setopt($ch1, CURLOPT_HEADER, 0);
    curl_setopt($ch1, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch1, CURLOPT_FAILONERROR, TRUE);
    $xml_str = curl_exec($ch1);
    curl_close($ch1);
$xml = new SimplexmlElement($xml_str);
echo '<div id="weather">';
foreach($xml->weather as $item) {

foreach($item->forecast_information as $new) {
            echo $new->city['data'];
            }

        foreach($item->current_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
        echo $new->condition['data'];
            echo $new->temp_f['data'];
            echo $new->temp_c['data'];
            echo $new->humidity['data'];
            echo $new->wind_condition['data'];
            echo '</div>';
            }

        foreach($item->forecast_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
            echo $new->day_of_week['data'];
            echo $new->condition['data'];
            echo $new->low['data'];

            echo '</div>';
            }

    }

echo '</div>';
}

getWeather();

So how would I format the layout of the output page? See here:

I just want to organize it better and label the output text (ie. Humidity, Conditions,Wind, etc...
