如何检查多维数组中是否存在某些索引的重复值？

Question

My problem is i have a multidimensional array posting from form to php, now i want to checking if duplicate values of some indexes exist in multi dimensional array or not? e.g:

$data=Array
(
    0 => Array
    (
        uid => '100',
        name => 'Sandra Shush',
        type => 'abc'
    ),
    1 => Array
    (
        uid  => '101',
        name => 'Sandra Shushtext',
        type => 'xyz'
    ),
    2 => Array
    (
        uid => '100',
        name => 'Sandra Shush',
        type => 'abc'
    )
);

here name and type of index 1 and 2 are same, so how can i check it?

I am familiar with

$key = array_search('abc', array_column($data, 'type'));

but it is for duplication of single column value in multi rows, in my situation if multi column of same rows same with multi column of any other row then record will be consider as duplicate.

Any help should be appreciated, Thanks in advance.

Answer 1

I achieved above scenario like this:

Dont know which one is best mine or other's who posted answers.

foreach($data as $key => $row)
{
    $combinedarr[] = array("name"=>$row["name"],"type"=>$row["type"]);
}
//chck if same facilitiy is being visit on same date twice
$countcomb = count($combinedarr);
$uniquearr = array_unique($combinedarr, SORT_REGULAR);
if($countcomb==count($uniquearr)){
}else{
    //yes duplicate exists
};

Thanks again for those who answered.
