<p>What does the following code do? A link to something in the PHP manual would also be nice.</p>

<pre><code>if ($_SERVER['SERVER_PORT'] &lt;&gt; 443) {
    doSomething();
}
</code></pre>

Same as !=, "Not equal"
```
```
false <> true // operator will evaluate expression as true
false != true // operator will evaluate expression as true
```
```
