title: Find common values in multiple arrays with PHP
body: <p>I need to find common values in multiple arrays. Number of arrays may be infinite. 
  Example (output from <code>print_r</code>)</p>
  
  <pre><code>Array1
  (
      [0] =&gt; 118
      [1] =&gt; 802
      [2] =&gt; 800
  )
  Array2
  (
      [0] =&gt; 765
      [1] =&gt; 801
  )
  Array3
  (
      [0] =&gt; 765 
      [1] =&gt; 794
      [2] =&gt; 793
      [3] =&gt; 792
      [4] =&gt; 791
      [5] =&gt; 799
      [6] =&gt; 801
      [7] =&gt; 802
      [8] =&gt; 800
  )
  </code></pre>
  
  <p>now, I need to find the values that are common on all 3 (or more if available) of them.... how do I do that?</p>
  
  <p>Thanx</p>
