            (
                [id] => 4083
                [player_name] => AD373
            )
    
        [1] => Array
            (
                [id] => 4084
                [player_name] => SM8
            )
    
        [2] => Array
            (
                [id] => 4085

Array 2

        )

    [1] => Array
        (

            [player_name] => WW8
        )

    [2] => Array
        (

            [player_name] => 8799         
        )

    [3] => Array
        (
            [id] => 4060
            [player_name] => SM8
        )
)

mycode

foreach ($array1 as $gkey => $gvalue) {
   $notexist = array();
   foreach ($array2 as $smkey => $smvalue) {
        
        if ($smvalue['player_name'] !== $gvalue['player_name']) {
             $notexist[] = $smvalue;
        }        
   }
}

Question: There will have 2 array, I want to compare this 2 array and find out the value that only appear in one array which is value player_name 8799. But looks like my code will store the wrong result. Does anyone can help on this ya :( ?

Try this:

<?php
$array1 = Array(
    0 => Array
        (
            'id' => 4083,
            'player_name' => 'AD373'
        ),

    1 => Array
        (
            'id' => 4084,
            'player_name' => 'SM8'
        ),

    2 => Array
        (
            'id' => 4085,
            'player_name' => 'WW8'
        )
);

$array2 = Array(
    0 => Array
        (
            'id' => 4046,
            'player_name' => 'AD373'
        ),

    1 => Array
        (
            'id' => 4080,
            'player_name' => 'WW8'
        ),

    2 => Array
        (
            'id' => 4045,
            'player_name' => 8799         
        ),

    3 => Array
        (
            'id' => 4060,
            'player_name' => 'SM8'
        )
);

foreach($array1 as $value){
    $temp1[] = $value['player_name'];
}

foreach($array2 as $value){
    $temp2[] = $value['player_name'];
}

$differences = array_merge(array_diff($temp1,$temp2), array_diff($temp2,$temp1));
print_r($differences);

Output:


Array
(
    [0] => 8799
)

look at this example

<?php
$array1 = array("a" => "green", "red", "blue", "red");
$array2 = array("b" => "green", "yellow", "red");
$result = array_diff($array1, $array2);

print_r($result);
?>
