Bug #16715: array_unique results in only one entry in the array

From: tlieske@thl-consulting.com Operating system: linux PHP version: 4.1.2 PHP Bug Type: Arrays related Bug description: array_unique results in only one entry in the array The following code should demonstrate that unusual behavior (becaue I'm still not convinced that this is a bug) $input = array ( array (1,1), array (1,2), array(1,2), array(1,1) ); $result = array_unique ($input); print_r($result); The result is : Array ( [0] => Array ( [0] => 1 [1] => 1 ) ) This was not what I was expecting. I was expecting the following result : Array ( [0] => Array ( [0] => 1 [1] => 1 ) [1] => Array ( [0] => 1 [1] => 2 ) ) This is the result You get if You use PHP Version 4.0.4pl1 and before for example. So it is up to You, if You call this a bug or if I just have missused the function array_unique because I was not using a one dimensional array. Hopefully that helps You and me.
