Use JSON in PHP 4 or PHP 5.1.x

Use JSON in PHP 4 or PHP 5.1.x : 

Here i will explain how to use JSON (json_encode() , json_decode()) in versions of PHP earlier than 5.2. Add the following custom function to use (json_encode() , json_decode()) this functions in php. IF u don't have this JSON PEAR Package You can download in HERE 

1. for json_encode() :

if (!function_exists('json_encode')) {
    function json_encode($content) {
        require_once 'classes/JSON.php';
        $json = new Services_JSON;
        return $json->encode($content);
    }
}
2. for json_decode() :

if (!function_exists('json_decode')) {
    function json_decode($content, $assoc=false) {
        require_once 'classes/JSON.php';
        if ($assoc) {
            $json = new Services_JSON(SERVICES_JSON_LOOSE_TYPE);
        }
        else {
            $json = new Services_JSON;
        }
        return $json->decode($content);
    }
}
