Re: Ordering an array

You'll have to break up and reassemble the names yourself. Assuming the filenames will always be of the form <alphabetic prefix><numeric string>.<extension> and the input and outputs are both one-dimensional arrays, you could do it as follows: function MySort($files) { unset($filebits); unset($newfiles); reset($files); while (list(, $name) = each($files)) { eregi('([[:alpha:]]+)([[:digit:]]+)(.*)', $name, $bits); $filebits[$bits[2]] = array($bits[1], $bits[3]); } ksort($filebits); reset($filebits); while (list($key, $data) = each($filebits)) { $newfiles[] = $data[0].$key.$data[1]; } return $newfiles; } Usual untested, off-the-top-of-head caveats apply; I also have the feeling there's probably a more efficient/elegant way to do this... If the file prefix or suffix (here, 'pw' and '.htm', respectively) are invariant, you could simplify and speed up the regular expression by passing the prefix and suffix as arguments to the MySort() function.
