notice when using file helper

Hi,

when I use

Code:

$file = get_filenames('images/gallery/thumbs', false);
for( $i = 0 ; $i <= count($file) ; $i++ )
{
       echo $file[$i] . '<br />';
}

I receive proper files but also


A PHP Error was encountered
Severity: Notice
Message: Undefined offset: 10
Filename: public/vertical_menu_page_view.php
Line Number: 99

Use < instead of <=

It's also recommended to do the count function outside of the loop, otherwise it will run on every single loop iteration. Not a big deal for small loops, but it can be time consuming for more involved loops.

Code:

$count = count($file);

for ($i = 0; $i < $count; $i++)
{
  // ...
}
