The array that you get from $message = explode ("|", $line) will be something like KEY VALUE 0 date1 1 head1 2 text1 with spaces around the text (which you may want to chop()) so you need something like 41> $message = explode ("|", $line); 42> 43> while (list (, $value) = each($message)) 44> { 45> echo "chop($value)<br>"; 46> }; The comma in Line 43 is important! Alternatively, you could use str_replace to change the ' | ' (that's space pipe space) to <BR> Cheers -- David Robley | WEBMASTER & Mail List Admin RESEARCH CENTRE FOR INJURY STUDIES | http://www.nisu.flinders.edu.au/ AusEinet | http://auseinet.flinders.edu.au/ Flinders University, ADELAIDE, SOUTH AUSTRALIA
