Let's do the table body now:

$Tbody->TDOut("New York");
But this is still getting kind of lengthy. Couldn't we save some more steps? How about trying this:


function TROut($message) { /*And NO comments about fish, please! ;)   */

PRINT "<TR>\n";
        while (
$i<$iterations) {
                if (
                if (
$this->TDOut ($message,$span);
$this->TDOut ($message);


Wow! That's a little more complicated. Let's break it down:
  • Line 3 splits the message on pipes and stores the pieces in the array $cells.
  • Line 4 stores the number of items (number of cells) in $iterations.
  • Line 6 begins our loop to go through these cell items.
  • Line 7 splits the cell data at the colon and stores them into the variables $message and $span.
  • Line 8 checks to see if a message was included. If not then it sets message to the default.
  • Line 9 checks to see if there was a span listed (i.e. the cell data had a colon with something behind it.
    • if so, Line 10 calls TDOut with the message and the number of cells it spans.
    • if not, Line 12 calls TDOut with just the message (TDOut will set $colspan to the default 1).
Lastly, we close out the row.
What this means is we can pass a single string to TROut that will contain all the necessary information to print out the entire row as long as the string is in the format celldata[:colspan]|celldata[:colspan]|......celldata[:colspan].
So, instead of all the work we did before, the headers and body of the table could be called like this:
$Tbody->TROut("Rod|Kreisler|Cortlandt|New York|USA");
Wow. That's a lot easier. But what if the data is in variables? Simply join the array:
