title: Cant find a way to compare array keys
body: <p>I've got these two arrays:</p>
  
  <pre><code>Array ONE
  (
      [39] =&gt; Dude, Harry [10%]
      [36] =&gt; Occonell, Tim [90%]
  )
  
  Array TWO
  (
      [1] =&gt; Person, Admin
      [2] =&gt; Snow, John
      [3] =&gt; Jane, Marry
      [14] =&gt; Kelchenko, Igory
      [18] =&gt; Bery, Grass
      [36] =&gt; Occonell, Tim
  )
  </code></pre>
  
  <p>I'm trying to delete value from second array, if it's key is equal to first one. So my array should look like:</p>
  
  <pre><code>Array TWO
  (
      [1] =&gt; Person, Admin
      [2] =&gt; Snow, John
      [3] =&gt; Jane, Marry
      [14] =&gt; Kelchenko, Igory
      [18] =&gt; Bery, Grass
  )
  </code></pre>
  
  <p>I have attempted to find an answer else where, but I could not find one.</p>
