title: PHP returns an error about an unexpected T_DOUBLE_ARROW
body: <p>I am getting this error:</p>
  
  <blockquote>
    <p>Parse error: syntax error, unexpected T_DOUBLE_ARROW in /clientdata/zeus-dynamic-1/i/n/incard.com.au/www/newsite/system/classes/core.php on line 36</p>
  </blockquote>
  
  <p>and on line 36 I have this code:</p>
  
  <pre><code>if($this-&gt;postcode =&gt; 1000 &amp;&amp; $this-&gt;postcode =&lt; 1999 || $this-&gt;postcode =&gt; 2000 &amp;&amp; $this-&gt;postcode =&lt; 2599 || $this-&gt;postcode =&gt; 2619 &amp;&amp; $this-&gt;postcode =&lt; 2898 || $this-&gt;postcode =&gt; 2921 &amp;&amp; $this-&gt;postcode =&lt; 2999)
  </code></pre>
  
  <p>I am wondering why this would be, and how to correct it.</p>
