How can error reporting be effectively utilized in PHP to troubleshoot issues like file upload failures?

When troubleshooting file upload failures in PHP, it is essential to utilize error reporting to identify the root cause of the issue. By enabling error reporting and displaying detailed error messages, developers can quickly pinpoint issues such as file size limitations, incorrect file types, or insufficient permissions. This information can help in resolving the problem and ensuring successful file uploads. 

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

// Handle file upload process
if ($_FILES['file']['error'] > 0) {
    echo 'File upload error: ' . $_FILES['file']['error'];
} else {
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
    echo 'File uploaded successfully!';
}
