Re: re-keying an array

Just a quick follow-up question on that: Curt Zirzow wrote:

foreach(array_slice($filenames, 0, 2) as $filename) { $files[] = "path/to/" . $filelname; }

Will a function (such as the array_slice here) in a foreach statement get re-evaluated for each iteration, or is it evaluated just once? In other words, is there anyhing gained by doing: $short_array = array_slice($filenames, 0, 2); foreach($short_array as $filename) { $files[] = "path/to/" . $filelname; } /Mattias
