Php 比较两个多维数组

Php：比较Php中的2个多维数组 我有02个阵列，我想比较一下。

    $first = array(
          0 => array(
                 "id" => 45,
                 "name" => "chicago"
               ),
          1 => array(
                 "id" => 78,
                 "name" => "LA"
               ),
    );

    $second = array(
          0 => array(
                 "id" => 45,
                 "name" => "chicago"
               ),
          1 => array(
                 "id" => 78,
                 "name" => "LA"
               ),
          2 => array(
                 "id" => 95,
                 "name" => "Washington"
               ),
    );

比较两个阵列后，我希望

    $cityMissing =array (
                  0 => array(
                     "id" => 95,
                     "name" => "Washington"
                   );


**Please, I need your help.**

请告诉我们您首先尝试了什么，以便我们可以帮助您修复它。这将是一个注释。它不起作用，我有一个错误：注意：数组到字符串的转换

$arrayFirst = array("0" => array("id", "45") );
$arraySecond = array("0" => array("id", "45"), "1" => array("id", "95"));

$result = array_diff_assoc($arraySecond, $arrayFirst);

print_r($result);

    [1] => Array

        $ret = array();

        // Loop over the "to" array and compare with the others
        foreach($a as $key=>$val){
            // We should compare type first
