PHP - Concatenating 2 objects

Question

I have 2 objects.

Here is the output of the objects when I print them out with print_r method of the PHP.

Oject #1;

stdClass Object ( [id] => 1 [portal_id] => 1 [name=> NEVZAT )

Object #2;

stdClass Object ( [surname] => YILMAZ)

I want to concatenate these 2 objects to each other so at the end of the process I need an Object which contains all of the variables of the 2 objects;

stdClass Object ( [id] => 1 [portal_id] => 1 [name=> NEVZAT [surname] => YILMAZ )

A simple way would be to temporarily cast the objects to arrays, merge those arrays, then case the resulting array back to a stdClass object.

$merged = (object) array_merge((array) $object_a, (array) $object_b);

looks OK, thank you, but I want to know if this is the only way. Because it may cause some performance issues, there are lots of type castings. – WhoSayIn Jun 05 '12 at 10:18

Of course it is not the **only** way. Re. performance issues, my only advice would be to worry about performance when performance becomes an issue. – salathe Jun 05 '12 at 11:06

Just copy over the attributes like so:

// assume $o1 and $o2 are your objects
// we copy $o1 attributes to $o2
foreach ($o1 as $attr => $value) {
        $o2->{$attr} = $value;
}
