Unexpected T_FUNCTION?
<p>I've question about solving in php version 5.2.7, where i get an error Parse error: syntax error, unexpected T_FUNCTION in /home/ ... /mainMenu.php on line 56. The code is</p>

<pre><code>class MainMenu {
    ...
    private static function toRec($arr) {
        ...

        usort($newArr, function($a, $b) {//this was line 56
            return $a['nav_order'] - $b['nav_order'];
        });
        ...
    }
    ...

}
</code></pre>

<p>What is alternative for php 5.2?</p>

<p>Thank you</p>
