title: Compare multiple values in PHP
body: <p>I'd like to go from this:</p>
  
  <pre><code>if($var == 3 || $var == 4 || $var == 5 || $var =='string' || $var == '2010-05-16') {
     // execute code here
  }
  </code></pre>
  
  <p>to this:</p>
  
  <pre><code>if($var == (3, 4, 5, 'string', '2010-05-16')) { // execute code here }
  </code></pre>
  
  <p>Seems very redundant to keep typing <code>$var</code>, and I find that it makes it a bit cumbersome to read.  Is there a way in PHP to do simplify it in this way?  I read on a post here that when using XQuery you can use the = operator as in <code>$var = (1,2,3,4,5)</code> etc.</p>
