Yii2 Custom Class - namespace error

I am trying to create a custom class that can be called to convert dates and times for MySQL.

I am using the Yii2 Basic template

I have created a folder and a file in components called Convert.php

<?
namespace app\components;

use Yii;

class Convert
{
    const DATE_FORMAT = 'php:Y-m-d';
    const DATETIME_FORMAT = 'php:Y-m-d H:i:s';
    const TIME_FORMAT = 'php:H:i:s';

    public static function toMysql($dateStr, $type='date', $format = null) {
        if ($type === 'datetime') {
              $fmt = ($format == null) ? self::DATETIME_FORMAT : $format;
        }
        elseif ($type === 'time') {
              $fmt = ($format == null) ? self::TIME_FORMAT : $format;
        }
        else {
              $fmt = ($format == null) ? self::DATE_FORMAT : $format;
        }
        return \Yii::$app->formatter->asDate($dateStr, $fmt);
    }   
}

?>

I then try and call this method in my controller

use app\components\Convert;

...

public function actionCreate()
{
    ...
    $model->date_of_birth = Convert::toMysql($model->date_of_birth);
    ...
}

However I am getting the following error

Unable to find 'app\components\Convert' in file: /var/www/html/portal/components/Convert.php. Namespace missing?

I am probably missing something simple, but I cannot see it.

Thanks for your help.

From the comments, I have found that the error was a simple mistake, the opening tag should have been 

<?php

This error simply means php cannot find the namespace in this file, and since the namespace seems to be correct, it is probably a php opening tag error.

Depending on your server php configuration, short open tags could be disabled, you should always use <?php.

You need to extend base Component from Yii2:

<?php
namespace app\components;
use yii\base\Component;

use Yii;

class Convert extends Component
{
    const DATE_FORMAT = 'php:Y-m-d';

And then put in config/web.php

'components' => [
    'convert' => [
       'class' => 'app\components\Convert',
     ],
]

and access it as 

$model->date_of_birth = Yii::$app->convert->toMysql($model->date_of_birth);
