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);
}
