What is the recommended way to save the contents of a variable to a text file in PHP?

To save the contents of a variable to a text file in PHP, you can use the `file_put_contents()` function. This function allows you to write data to a file, creating the file if it doesn't already exist. You simply pass the file path and the variable's contents to the function to save it to a text file. 

// Variable containing data to be saved
$data = "Hello, World!";

// File path to save the data
$file = 'output.txt';

// Save the contents of the variable to a text file
file_put_contents($file, $data);
