Can't detect MIME type when using Zend Zend_File_Transfer_Adapter_Http !

I am writing a small script to upload and detect MIME type, using Zend Framework. For the design purpose, I can't use Zend_Form but normal instead. And I simply apply from the manual :

$adapter = new Zend_File_Transfer_Adapter_Http(); $files = $adapter->getFileInfo(); $mime = $files->getMimeType();

But the system inform that the funcion getMimeType() does not existed. Then, I tried:

$adapter = new Zend开发者_如何转开发_File_Transfer(); $files = $adapter->getFileInfo(); $mime = $files->getMimeType();

This time, it didn't work either. So, how can I get the MIME type ?

Thank you so much for your help

I believe $files in both of your snippets would just be a simple array, and each element should contain a key to indicate the type, like so:

$files = $adapter->getFileInfo();

foreach ($files as $file) {
    // Print the MIME Type for $file
    echo $file['type'];
}

The Zend_File_Transfer_Adapter_Abstract class defines the code for determining the MIME type. It depends on Fileinfo class/extension or the mime_content_type() function (part of an older version of Fileinfo, I believe).

PHP 5.3 includes Fileinfo by default. Versions prior to 5.3 require the use of the PECL extension:
