$file = 'my_file.txt'; $data = 'Hello World!'; file_put_contents($file, $data);
$file = 'my_file.txt'; $data = array('apple', 'banana', 'orange'); file_put_contents($file, implode("\n", $data));In this example, we are saving an array of fruits to a file called "my_file.txt". The implode function is used to convert the array into a string with each element separated by a new line character. File saving is a core functionality in PHP, and therefore no external package or library is required for this task.
