http://php.net/manual/en/book.json.php

In particular you might want to look at json_decode()

A small example: 

<?php

function JSONPrepare($json) {
    // This will convert ASCII/ISO-8859-1 to UTF-8.
    // Be careful with the third parameter (encoding detect list), because
    // if set wrong, some input encodings will get garbled (including UTF-8!)
    $input = mb_convert_encoding($json, 'UTF-8', 'ASCII,UTF-8,IS0-8859-1');

    // Remove UTF-8 BOM if present, json_decode() does not like it.
    if (substr($input, 0, 3) == pack("CCC", 0xEF, 0xBB, 0xBF)) {
        $input = substr($input, 0, 3);
    }

    return $input;
}

foreach (json_decode(JSONPrepare($my_json), true) as $k => $v) {
    // process the array here
}
?>

*"Yeah I know it should be done with json_decode. But I don't know how to do it."*

Ok, somehow you're getting data into a variable, let's say $data

$array=json_decode($data, true);

will convert that into an array which in this case has other arrays and variables inside id

To see the whole thing print_r($array); and view source code, or echo '<pre>'; print_r($array);

So to get to the bits you want to need to traverse the array, but what you want is in one element of many in an array locations so we need to iterate through them

foreach ($array['response']['deals']['active']['locations'] as $location)
{
     echo 'id:'.$location['id'];
     echo 'lat':$location['lat'];
     //ect
}

or you could pick the first one

echo $array['response']['deals']['active']['locations'][0]['id'];

json_decode will convert the json into a PHP object.

Using $response = json_decode($json); where $json is the JSON you have posted above, then:

echo $response->deals->business->id; // 11009
echo $response->deals->business->locations[0]->id; //974228 
echo $response->deals->ypit_url; // http://yipit.com/h...y-boot-camp-up-to-81-off-42/

You can even get those data as array which will be easy to parse than objects.

$parsedData = json_decode($jsondata, 1);

print_r ($parsedData);
