title: check multiple values exists php array
body: <p>I have an array in PHP</p>
  
  <pre><code>$permission = array( "admin", "moderator", "guest"  );
  </code></pre>
  
  <p>and i have another array</p>
  
  <pre><code>$userRoles = array( "admin", "moderator" );
  </code></pre>
  
  <p>I checked with <code>in_array</code> but it doesn't work with multiple values.</p>
  
  <p>How can i check atleast one value in <code>$userRoles</code> exists on <code>$permission</code> without looping ?</p>
  
  <p>Thanks in advance.</p>
