How can error reporting in PHP help identify issues with file uploads and what are best practices for implementing it?

Error reporting in PHP can help identify issues with file uploads by providing detailed error messages when something goes wrong during the upload process. This can include issues such as file size limits being exceeded, file type restrictions not being met, or problems with file permissions. By enabling error reporting and handling these errors appropriately, developers can quickly diagnose and resolve issues with file uploads. 

// Enable error reporting for file uploads
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Handle file upload
if($_FILES['file']['error'] !== UPLOAD_ERR_OK){
    echo 'Error uploading file: ' . $_FILES['file']['error'];
    // Handle error appropriately (e.g. display message to user, log error)
} else {
    // Process file upload
}
