basename & dirname in Perl

These two Perl functions implement approximations of the UNIX utilities `basename` and `dirname`, though basename() automatically strips off the last extension no matter what.

sub basename($) {
 my $file = shift;
 $file =~ s!^(?:.*/)?(.+?)(?:\.[^.]*)?$!$1!;
 return $file;
}

sub dirname($) {my $file = shift; $file =~ s!/?[^/]*/*$!!; return $file; }

Image aggregator

This PHP snippet outputs the contents of a table (beginning & ending tags not included) containing all the images from the current directory.

<?PHP
 $columns = 3;
 $im = glob("*.{gif,jpg,png}", GLOB_BRACE);
 $rows = ceil(count($im) / $columns);
 for ($i = 0; $i < $rows; $i++) {
  echo "\n<TR>";
  for ($j = $columns*$i; isset($im[$j]) && $j - $columns*$i < $columns; $j++) {
   echo "<TD>$im[$j]<BR><IMG SRC='$im[$j]'></TD>";
  }
  echo "</TR>";
 }
?>
