How to set $this in PHP5

[Chung Leong]

I ran into this problem trying to run a PHP4 program in PHP5:

A class implements persistence by serializing itself and saving the string
to a file. In the constructor, the object restores itself by setting $this
to the result from unserialize(). In PHP4, this is legal. In PHP5 I get an
error. How do I fix this aside from manually copying the object properties?

If you don't want to copy the properties, the only thing you can do is
storing the unserialized object as a class property and use it from there.

Otherwise, you could use the reflectionObjec t class to simplify the task of
copying the properties:

$ro = new reflectionObjec t($obj);
foreach ($ro->getProperties( ) as $propObj) {
$this->{$propObj->name} = $obj->{$propObj->name};
}
