PHP taking an array of objects, get rid of the duplicates one

Question

I have this array:-

$arr
: array = 
  0: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  1: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  2: object(myObject) = 
    id: string = 189
    CaseNo: string = 3
    strname: string = Amazon
    strContact: string = Jules

As you can see, the two first objects in the array are repeated, how can get the same array without the repeated object, meaning:

$arr
: array = 
  0: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  1: object(myObject) = 
    id: string = 189
    CaseNo: string = 3
    strname: string = Amazon
    strContact: string = Jules

Please notice that this is an example array. The number of items in the array can be more than three and the number of repeated objects inside of it can be more than two.

Thanks a lot

Use array unique function which used to remove duplication

 $a = array(
        0 => array (
            "ID" => 188,
            "CaseNo" => 1,
            "strname" => 'Apple',
            "strContact" => 'Alies'

        ),
        1 => array (
             "ID" => 188,
            "CaseNo" => 1,
            "strname" => 'Apple',
            "strContact" => 'Alies'

        ),
        2 => array (
            "ID" => 189,
            "CaseNo" => 1,
            "strname" => 'Amazon',
            "strContact" => 'Jules'

        ),
);
echo "<pre>";
$ab = array_map("unserialize", array_unique(array_map("serialize", $a)));
print_r($ab);
