Note Submitter: jfdsmit at gmail dot com ---- json_encode also won't handle objects that do not directly expose their internals but through the Iterator interface. These two function will take care of that: <?php /** * Convert an object into an associative array * * This function converts an object into an associative array by iterating * over its public properties. Because this function uses the foreach * construct, Iterators are respected. It also works on arrays of objects. * * @return array */ function object_to_array($var) { $result = array(); $references = array(); // loop over elements/properties foreach ($var as $key => $value) { // recursively convert objects if (is_object($value) || is_array($value)) { // but prevent cycles if (!in_array($value, $references)) { $result[$key] = object_to_array($value); $references[] = $value; } } else { // simple values are untouched $result[$key] = $value; } } return $result; } /** * Convert a value to JSON * * This function returns a JSON representation of $param. It uses json_encode * to accomplish this, but converts objects and arrays containing objects to * associative arrays first. This way, objects that do not expose (all) their * properties directly but only through an Iterator interface are also encoded * correctly. */ function json_encode2($param) { if (is_object($param) || is_array($param)) { $param = object_to_array($param); } return json_encode($param); }
