Yaf_Request_Simple::getFiles() is a method in PHP's Yaf framework that is used to retrieve files uploaded via HTTP POST request. It returns an array containing the uploaded files, where each element represents a file with details such as filename, temporary location, file size, etc.

To use Yaf_Request_Simple::getFiles(), you need to create an instance of Yaf_Request_Simple class and call the method on that instance.

Here's an example to demonstrate its usage:

php
// Create an instance of Yaf_Request_Simple
$request = new Yaf_Request_Simple();

// Get the uploaded files using getFiles() method
$uploadedFiles = $request->getFiles();

// Loop through the uploaded files array
foreach ($uploadedFiles as $file) {
// Get file details
$filename = $file['name']; // Original filename
$tmpLocation = $file['tmp_name']; // Temporary location
$fileSize = $file['size']; // File size

// Process the uploaded file as per your needs
// For example, move the uploaded file to a permanent location
move_uploaded_file($tmpLocation, "/path/to/destination/{$filename}");

// You can also perform additional validations on the uploaded file
// For example, check the file extension, MIME type, etc.
}


In this example, we create an instance of Yaf_Request_Simple, call getFiles() method on that instance, and retrieve the uploaded files. Then, we loop through the array and extract the necessary file details for further processing, like moving the file to a permanent location or performing additional validations.
