Share Constants Between PHP and JavaScript [duplicate]

Answer 1

I would use json_encode. You will have to convert the class to an associative array first.

$constants = array("RESOURCE_TYPE_REGISTER"=>2, "RESOURCE_TYPE_INFO"=>2);
echo json_encode($constants);

You could also use reflection to convert the class to an associative array if you would prefer to use a class.

function get_class_consts($class_name)
{
    $c = new ReflectionClass($class_name);
    return ($c->getConstants());
}

class Constants {
    const RESOURCE_TYPE_REGSITER = 2;
    const RESOURCE_TYPE_INFO = 1;
}

echo json_encode(get_class_consts("Constants"));
