<p>I've got a php script. Most of the time the script returns html, which is working fine, but on one occasion (parameter ?Format=XML) the script returns XML instead of HTML.</p>

<p>Is there any way to change the returned mime type of the php output on the fly from text/html to text/xml or application/xml?</p>

```
```
header('Content-type: application/xml');
```
```
More information available at the PHP documentation for
```
header()
```
