I have an single multi-dimensional array, and want to compare its own value array's are duplicate or not.

Let the array is like :

$userdb = Array
(
    (0) => Array
        (
            'college' => 'college1',
            'name' => 'Anil Kumar',
            'city' => 'bikaner'
        ),

    (1) => Array
        (
            'college' => 'college2',
            'name' => 'Tanu Shree',
            'city' => 'bikaner'
        ),

    (2) => Array
        (
            'college' => 'college1',
            'name' => 'Anil Kumar',
            'city' => 'bikaner'
        )
);

Here two indexes are same, index 0 and 2. How can I compare the whole sub-array of this multi-dimensional array for my single array $userdb. I want to compare whole index's array not only fields.

`$array != array_unique($array,SORT_REGULAR)` to check if there's duplicates in it. – apokryfos Oct 10 '16 at 11:46
`function checkCsvRowDuplicate($address) { $addressCsv = $address; $array_new = array(); $i = 0; foreach ($addressCsv as $key => $addr) { # code... foreach ($addr as $k => $value) { $array_new[$i] .= $value.", " ; } $i++; } $duplicate = (array_count_values($array_new)); $duplicate = array_values($duplicate); if(in_array('2',$duplicate)) { return "duplicate"; } else { return "unique"; } }` – Yogita Oct 10 '16 at 13:10
