Are there any specific functions or methods in PHP that can help with formatting data for file writing?

When writing data to a file in PHP, it's important to properly format the data to ensure readability and consistency. One way to achieve this is by using the `fwrite()` function along with formatting methods like `sprintf()` or `json_encode()` to structure the data before writing it to the file. 

// Example using sprintf() to format data before writing to a file
$data = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

$formattedData = sprintf("Name: %s, Age: %d, Email: %s", $data['name'], $data['age'], $data['email']);

$file = fopen('data.txt', 'w');
fwrite($file, $formattedData);
fclose($file);
