What are some alternative methods, besides "echo" or "readfile", that can be used to achieve the desired outcome?

One alternative method to achieve the desired outcome of outputting a file's contents in PHP is to use the "file_get_contents" function. This function reads the entire contents of a file into a string, which can then be echoed out to the browser. 

$file_contents = file_get_contents('file.txt');
echo $file_contents;
