What server configurations are necessary to support uploading and extracting various file formats with PHP?

To support uploading and extracting various file formats with PHP, the server must have the necessary configurations such as increasing the upload_max_filesize and post_max_size limits in the php.ini file, enabling file_uploads, and setting the max_execution_time to allow for longer processing times. Additionally, the server should have the required libraries installed to handle different file formats like ZipArchive for extracting zip files.

// Increase upload file size limits
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');

// Enable file uploads
ini_set('file_uploads', 'On');

// Set maximum execution time
ini_set('max_execution_time', 300); // 5 minutes

// Check if ZipArchive extension is available
if (!extension_loaded('zip')) {
    die('ZipArchive extension is not available.');
}
