What alternative methods can be used to achieve the goal of writing variables to a file on a server without FTP in PHP?

One alternative method to achieve the goal of writing variables to a file on a server without FTP in PHP is to use the file_put_contents() function. This function allows you to write data to a file on the server without the need for FTP access. You can simply provide the file path and the data you want to write to the file as arguments to the function.

$data = "Hello, world!";
$file = 'example.txt';

file_put_contents($file, $data);
