Php array unique comparing 2 types

Question

I have data (more than 10000) from excel, data format looks like,

Example :

Message | Number 

Test 1    021
Test 2    033
Test 3    022
Test 3    022
Test 3    033
Test 2    022
Test 2    021

Input accepted should be

same number & different message
different number & same message
different number & different message

I'm trying to make validation, using array, I tried array_unique, but I can only use 1 type,

$arrayCon[$i]=array("message"=>$message, "number"=>$number);
$realArray=array_unique($arrayCon["number"]);

How do I compare 2 type within 1 array ?

You need to apply array_unique() on the array itself, specifying the SORT_REGULAR flag to compare each element:

$realArray = array_unique($arrayCon, SORT_REGULAR)

You can take advantage of JSON and thus make the data row a string, so array_unique is usable:

$source=array();
foreach($database as $row)
{
    $source[]=json_encode(array("message"=>$row[0],"number"=>$row[1]));
}
$unique=array_map(function($str){
    return json_decode($str,true);
},array_unique($source));

Online demo
(I'm behind a proxy right now that seems to mess up with 3v4l.org's result output. If you can't see the result, please let me know)

print_r on my localhost outputs:

Array
(
    [0] => Array
        (
            [message] => Test 1
            [number] => 021
        )

    [1] => Array
        (
            [message] => Test 2
            [number] => 033
        )

    [2] => Array
        (
            [message] => Test 3
            [number] => 022
        )

    [4] => Array
        (
            [message] => Test 3
            [number] => 033
        )

    [5] => Array
        (
            [message] => Test 2
            [number] => 022
        )

    [6] => Array
        (
            [message] => Test 2
            [number] => 021
        )

)

This is completely unnecessary since 5.2.9, because you can use SORT_REGULAR flag on array_unique() to accomplish the same result.
