Hi pfraszczak:
This is NOT a bug.
because "" == NULL => TRUE.
if we change the test script to :
$a = array('street'=>'not-null-equal-value','number'=>'n1');
$b = array('street'=>'b1','number'=>'n1','test'=>null);
var_dump(array_diff($a,$b));
you will get the right result.

Description:
------------
I notice that array_diff return empty array when in second array we have entry
with null value. When i removed entry with test key - everything works fine.
Moreover it seems that null values in $a array don't brake array_diff
Test script:
---------------
$a = array('street'=>'','number'=>'n1');
$b = array('street'=>'b1','number'=>'n1','test'=>null);
var_dump(array_diff($a,$b));
Expected result:
----------------
array(1) {
["street"]=>
string(0) ""
}
Actual result:
--------------
array(0) {
}
