[quote author="ricardino" date="1254774320"]How would i get it to add a new line after every entry? at present its just stacking everything up together. Ive tried adding '/n' to the end of the $data variable but still no luck.[/quote]

Code:

$string = "My new line\n";
write_file('./path/to/file.php', $string, 'a');
