PHP explode doesn't work

Question

I have a text file and I want each line to be an element of an array.

$file = file("books.txt");
$split = explode("\n", $file);

Then if I try to print an element of the array:

echo "$split[0]";

I get no output.

`file` add a dollar sign; `split1` remove the 1; also what is the output of: `print_r($file);` ? — Rizier123, Mar 16 '15 at 15:40

Because file("books.txt") gives already an array resulting from exploding by newline, you can echo "$file[0]";, no need for further exploding.
