title: multidimensional array values matched with another index array values then remove values from multidimensional in PHP 7
body: <p>I am having below two arrays</p>
  
  <pre><code>    $firstArray = Array
  (
      [1] =&gt; Array
          (
              [MemberList] =&gt; Array
                  (
                      [0] =&gt; 100
                      [1] =&gt; 5d6
                      [2] =&gt; 5d7
                  )
          )
      [3] =&gt; Array
          (
              [MemberList] =&gt; Array
                  (
                      [0] =&gt; 5d8
                      [1] =&gt; 200
                  )
          )
  )
  
  
  $secondArray = Array
  (
      [0] =&gt; 100
      [1] =&gt; 200
  )
  </code></pre>
  
  <p>my question is if suppose <code>$secondArray</code> array values matched with <code>$firstArray</code> array then i have to remove the values from <code>$firstArray</code></p>
