multidimensional array difference php

Please check if I understand you correctly then this code snippet can help to you solve your problem. I have tested it for your specified problem only. if there are other testcases for which you want to run this, you can tell me to adjust the code.

$a1 = array(
    'a1' => array('a_name' => 'aaa', 'a_value' => 'aaaaa'),
    'b1' => array('b_name' => 'bbb', 'b_value' => 'bbbbbb'),
    'c1' => array('c_name' => 'ccc', 'c_value' => 'cccccc')
);

$a2 = array(
    'b1' => array('b_name' => 'zzzzz'),
);

$result = check_diff_multi($a1, $a2);
print '<pre>';
print_r($result);
print '</pre>';


function check_diff_multi($array1, $array2){
    $result = array();
    foreach($array1 as $key => $val) {
         if(isset($array2[$key])){
           if(is_array($val) && $array2[$key]){
               $result[$key] = check_diff_multi($val, $array2[$key]);
           }
       } else {
           $result[$key] = $val;
       }
    }

    return $result;
}

EDIT: added tweak to code.

this solution ah been very helpful to me I hope can help them in something, no matter what the array are in disarray.

function your_array_diff($arraya, $arrayb) {

    foreach ($arraya as $keya => $valuea) {
        if (in_array($valuea, $arrayb)) {
            unset($arraya[$keya]);
        }
    }
    return $arraya;
}

$a1 = Array
    (
    "0" => Array
        (
        "Empresa" => "TMC01",
        "Paga" => "13/01/2015",
        "ID" => "M2",
        "Valor" => "200",
        "Nombre" => "BONI"
    ),

    "1" => Array
        (
        "Empresa" => "TMC01",
        "Paga" => "13/01/2015",
        "ID" => "M1",
        "Valor" => "100",
        "Nombre" => "SUELDO"
    )
);

$b1 = Array
    (
    "0" => Array
        (
        "Empresa" => "TMC01",
        "Paga" => "13/01/2015",
        "ID" => "M1",
        "Valor" => "100",
        "Nombre" => "SUELDO"
    ),
    "1" => Array
        (
        "Empresa" => "TMC01",
        "Paga" => "13/01/2015",
        "ID" => "M2",
        "Valor" => "200",
        "Nombre" => "BONI"
    )
);

$resultado = your_array_diff($a1, $b1);

echo "<pre>";
echo print_r($resultado);
echo "</pre>";
