How do I prevent HTML output from PHP to show up in the browser?

Question

I'm quite new to PHP, so I suspect a stupid mistake. I've looked around for someone with a similar problem, but couldn't find any. So I have a PHP file that's supposed to output some HTML from a template (via Smarty). Instead of seeing the HTML rendered in Chrome, I see the HTML text itself. Here's the PHP code I'm using: ``` <?php header("Content-type: text/html; charset=utf-8"); ob_start(); include_once '../api/get_article.php'; $a_json = ob_get_clean(); $data = json_decode($a_json, true); require('./libs/Smarty.class.php'); $smarty = new Smarty(); $smarty->template_dir = './templates/'; $smarty->compile_dir = './templates_c'; $smarty->assign("title_text",$data['title']); $smarty->display('content.tpl'); ?> ``` I thought that it was a problem with encoding, but I made sure that everything uses UTF-8 (that is, MYSQL, the HTTP header, and the template file). What else could it be?

Accepted Answer

Smarty or the `get_article.php` script must be setting the content type header for you at some point. Try moving the line

```
header("Content-type: text/html; charset=utf-8");
```

All the way down to right above the `display` function to make sure it overrides any changes made earlier
