Why isn't this working? php rename()

Hi there,
I have this script below, which should rename a file with a word randomly picked from a txt file. Please could somebody tell me why it is not working?
Thanks

<?php
$filename="words.txt";
$words=file($filename);
shuffle($words);
$word = $words[0];

$old = 'tmp/today.php';
$new = 'tmp/'.$word.'.php';
rename($old, $new) or die("Unable to rename $old to $new.");
?>

PHP:

txt file

adult
aeroplane
air
airforce
airport
album
alphabet
apple
arm

PHP:

Thanks

 

You probably don't have rights to that files/folders.
Try to chmod it to 777

 

I've tried that.
I've also noticed that the script works fine just like this:

<?php
$old = 'tmp/today.php';
$new = 'tmp/tomorrow'.php';
rename($old, $new) or die("Unable to rename $old to $new.");
?>

PHP:

and the part which gets the words also works fine on its own:

<?php
$filename="words.txt";
$words=file($filename);
shuffle($words);
$word = $words[0];

echo $word;
?>

PHP:

It's just when you join them both together that it doesn't work :S

 

Try using trim()

$word = trim($words[0]);

PHP:

 

Finally!! Thanks for that

 

Try this :

<?php
copy('x.txt', 'copy.txt');
unlink('x.txt');
?>

Code (php):
