Error in json encoding and decoding in oAuth API - PHP

Question

I have created a oauth api in php using this example

http://code.google.com/p/oauth-php/wiki/ConsumerHowTo#OAuth_Consumer

And in the consumer page i am passing the params as json encoded string.

$key = '35345345345vertrtertert'; // fill with your public key 
$secret = 'h rtyrtyr767567567567'; // fill with your secret key
$url = "www.server.com/serverurl.php"; 

$options = array('consumer_key' => $key, 'consumer_secret' => $secret);
OAuthStore::instance("2Leg", $options);

$method = "POST";
$params = array(
           'radius' => '50',
           'latitude'=>'13.35',
           'longitude'=>'17.35'
     );
$params = json_encode($params);

And in the server page(ie serverurl.php) am printing the request using

print_r($_REQUEST);

And i decoded the string using json decode, but am getting this value as

    Array
(
    [radius] => 50
    [latitude] => 13_35
    [longitude] => 17_35
)

The . is replaced with _ in latitude and longitude How i can manage this

If it's consistently doing that, just do a str_replace(). It's a hacky solution, but it will work. — Matt

It seems that somewhere along the line in your encoding/decoding process the value is trying to be parsed a a number of something. If you truly want to work with these values as numbers, you shouldn;t set themn in your array as strings. Try this

$params = array(
    'radius' => 50,
    'latitude'=> 13.35,
    'longitude'=> 17.35
);

Note that I have removed the quotes around the numbers so they will be treated as numbers in the encoding process.

If i remove the quotes, foreach($_REQUEST as $key=>$value) { $array_val = $key; } $decode_val= json_decode($array_val,true); print_r($decode_val); this code print nothing

@Warrior What value do you get for var_dump($params) after json_encode is performed?

Shinu Thomas Over a year ago

string(48) "{"radius":50,"latitude":13.35,"longitude":17.35}"

And is that string intact in the raw $_POST variable in the receiving script? It might help to show the script you are posting to.

In the receiving script am getting Array ( [{"radius":50,"latitude":13_35,"longitude":17_35}] => )
