Note: is_object(null) returns false
This should actually be part of the input/output specification at the top of this page.
Unserializes data as returned by the standard PHP serialize() function. If the unserialized object is not an array, it will be converted to one, particularily useful if it returns a __PHP_Incomplete_Class.
<?php
/**
*
* @param string $data Serialized data
*
* @return array Unserialized array
*/
function unserialize2array($data) {
$obj = unserialize($data);
if(is_array($obj)) return $obj;
$arr = array();
foreach($obj as $k=>$v) {
$arr[$k] = $v;
}
unset($arr['__PHP_Incomplete_Class_Name']);
return $arr;
}
?>
I would expect a reference to is_a() function here.if you would test if an object is of an specific type use is_a()
