How to get MIME type of a file in PHP 5.5?

Question

I am using `mime_content_type()` in PHP 5.5 to get a MIME type, but it throws `fatal: error function not found`. How can I achieve this on PHP 5.5?

Accepted Answer

Make use of the `finfo()` functions.

A simple illustration:

```
<?php
$finfo = finfo_open(FILEINFO_MIME_TYPE);
echo finfo_file($finfo, "path/to/image_dir/image.gif");
finfo_close($finfo);
```

`OUTPUT :`

```
image/gif
```

Note : Windows users must include the bundled `php_fileinfo.dll` DLL file in php.ini to enable this extension.
