php reverse entries in a text file

in my guestbook entries are stored in a text file
how can I reverse entries (make first line last, last first and so on)

 

$lines = file ('entries.txt');
$f = fopen ('entries.txt', 'w');
fputs ($f, array_reverse ($lines));
fclose ($f);

PHP:

 

Cool site it's good code for array reverse, more usefull for me.

 

Come again?

 

1.
$lines = file ('entries.txt');
2.
$f = fopen ('entries.txt', 'w');
3.
fputs ($f, array_reverse ($lines));
4.
fclose ($f);
