How can PHP handle errors when creating folders and files?

When creating folders and files in PHP, errors can occur if the directory doesn't exist, permissions are insufficient, or the file already exists. To handle these errors, you can use functions like `mkdir()` and `file_put_contents()` along with error handling techniques like try-catch blocks or checking return values for errors. 

try {
    $folderPath = 'path/to/folder';
    if (!file_exists($folderPath)) {
        mkdir($folderPath, 0777, true);
    }
    
    $filePath = 'path/to/file.txt';
    if (!file_exists($filePath)) {
        file_put_contents($filePath, 'Hello, World!');
    } else {
        throw new Exception('File already exists');
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
