title: PHP remove array keys
body: <p>I have </p>
  
  <pre><code>Array ( [0] =&gt; 2088 [1] =&gt; 2087 [2] =&gt; 2091 [3] =&gt; 2083 [4] =&gt; 2086 [5] =&gt; 2085 [6] =&gt; 2084 [7] =&gt; 2092 [8] =&gt; 2089 [10] =&gt; 2122 [11] =&gt; 2122 )
  </code></pre>
  
  <p>As you can see i don't have array key number 9</p>
  
  <p>How can i move other keys down so [9] => 2122 [10] => 2122 ?</p>
  
  <p>Thanks</p>
