one suggestion,
why are you using ereg? beside the fact that it is vastly more resource
intensive than preg and slower, neither is needed because substr is faster
than both.
while ...
$extension = strtolower(substr($file, -4));
if ($extension != '.jpg'){ continue; }
whatever you want to do with the jpg from here
end
you could also use fnmatch to pattern match for file names. you could even
use glob()...
$directory = 'images';
$extension = '*.jpg';
chdir($directory);
foreach (glob($extension) as $image)
{
echo '<img src="' . $directory . '/' . $image . '" class="pad1em">';
}
i personally prefer glob() for such things since it requires less code to
get what you want.
anyway...there's always more than one way to skin a cat. ;^)
