PHP and Classes Page 5

Let’s do the table body now:

<TR>
<?php
$Tbody->TDOut("Kreisler");
$Tbody->TDOut("Rod");
$Tbody->TDOut("Cortlandt");
$Tbody->TDOut("New York");
$Tbody->TDOut("USA");
?>
</TR>

But this is still getting kind of lengthy. Couldn’t we save some more
steps? How about trying this:

<?php
function TROut($message) { /*And NO comments about fish, please! ;)   */
        PRINT "<TR>n";
        $cells=explode("|",$message);
        $iterations=count($cells);
        $i=0;
        while ($i<$iterations) {
                list($message,$span)=explode(":",$cells[$i]);
                if (strlen($message)<1) $message="&nbsp";
                if ($span){
                        $this->TDOut ($message,$span);
                }else{
                        $this->TDOut ($message);
                }
                $i++;
                }
        PRINT "</TR>n";
}
?>

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:

<TABLE>
<?php
$Theader->TROut("Name:2|Address:3");
$Theader->TROut("First|Last|City|State/Province|Country");
$Tbody->TROut("Rod|Kreisler|Cortlandt|New York|USA");
?>
</TABLE>

Wow. That’s a lot easier. But what if the data is in variables? Simply
join the array:

<?php
$message=join($arry,"|");
$Tbody->TROut($message);
?>
