Dump Duplicate Arrays

[Pico_Train]

Hi there! I've just tried to figure this out but I can't seem to get my head around it. In the array below, you can see that the arrays [0] and [1] are the same. I'd like to get rid of one of them if the values of var2 are equal, where $array[0]['var2'] = $array[1][var2] so I don't have a duplicate, preserving the array key does not matter. In the end I will only have a list of arrays without any dups! Thanks for the help!

$array[0] =Array
(
'var' => 'value',
'var1' => 'value1',
'var2' => 'value2',
);

$array[1] =Array
(
'var' => 'value',
'var1' => 'value1',
'var2' => 'value2',
);
$array[2] =Array
(
'var' => 'value3',
'var1' => 'value4',
'var2' => 'value5',
);

Sorry if I'm completely misunderstanding your question, but aren't you just wanting to compare two array elements and then unset one array if the elements are the same?

if($array[0]['var2'] == $array[1]['var2'])
{
// Unset (delete) the first aray
unset($array[0]);
}

Yes essentially. I thought of the above as well but didn't actually try it out. Will give it a bash now.

Have you looked at array_diff [us3.php.net]?
