Use file() function to read a variable name, not a literal name.

[walterbyrd]

I know I can use the file() function to read a file into an array by
providing a literal file name between single quotes:

$lines = file('literal_f ile_name');

But, what if I want file() to use a variable name?

$variable_file_ name = "literal_file_n ame";
$lines = file($variable_ file_name);

Of course, that example won't work. But what will?

Of course, that example will work. Why would you think otherwise?
