Answer 1

Try this example

$json = '{"foo-bar": 12345}';

$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345

http://php.net/manual/en/function.json-decode.php

NB - two negatives makes a positive . :)

Answer 2

Seems like you forgot the ["value"] or ->value:

echo $data[0]->weather->weatherIconUrl[0]->value;

Answer 3

If you use the following instead:

$json = file_get_contents($url);
$data = json_decode($json, TRUE);

The TRUE returns an array instead of an object.

Answer 4

This appears to work:

<?php

$url = 'http://www.worldweatheronline.com/feed/weather.ashx?q=schruns,austria&amp;format=json&amp;num_of_days=5&amp;key=8f2d1ea151085304102710%22';
$content = file_get_contents($url);
$json = json_decode($content, true);

foreach($json['data']['weather'] as $item) {
    print $item['date'];
    print ' - ';
    print $item['weatherDesc'][0]['value'];
    print ' - ';
    print '<img src="' . $item['weatherIconUrl'][0]['value'] . '" border="0" alt="" />';
    print '<br>';
}

If you set the second parameter of json_decode to true, you get an array, so you cant use the -> syntax. I would also suggest you install the JSONview Firefox extension, so you can view generated json documents in a nice formatted tree view similiar to how Firefox displays XML structures. This makes things a lot easier.
