I would like to check if a PHP object has a property. For PHP5 I could use
if (property_exists($object, "foo")) {...}
but how can I do the same in PHP4?

You can use get_object_vars and check the resulting array if your property exists.
Please refer to the the documentation on get_object_vars here: http://php.net/manual/en/function.get-object-vars.php

In the same vein:
$obj_arr = (array)$object; print isset($obj_arr["foo"]);/***
Just as you would do for PHP5, you can apply the same concept for PHP 4.
***/
//$data is a JSON object am receiving from a server.
$data = json_decode(stripslashes($_REQUEST['data']));
/****
Applying the same property_exists method but remember to keep both object/class
and the property to check for in single quotes.
*****/
if (property_exists('data', 'content'))
{
$content = $data->content;
}
