horizontal results from xml feed

stitchlips

I am trying to show the contents of my for each loop horizontally instead of vertically just like it was mentioned in this thread.
http://phpbuilder.com/board/showthread.php?t=10341280

This method in this thread would work but I am not using a database. I am getting my data from an xml feed.

Here is some simple sample code

<?php 
foreach($xml->Foods->Food as $Food){ 
$title = $Food->Title ; 
echo $title; 
?>

This would display the results like

title1
title2
title3

I would like

title1 title2 title3

Thanks!

No it won't... it'll actualy display them like:

title1title2title3

since you didn't separate them with a space or new line character.

Ok your right. I had the whole thing wrapped in a p tag and that was making it display vertical.

This is the correct code.

<?php 
foreach($xml->Foods->Food as $Food){ 
$title = $Food->Title ; 
?>
                   <table width="100%" border="0" cellspacing="0" cellpadding="1">
  <tr>
    <td><?php echo $title; ?></td>
  </tr>
</table>

                          <?php } ?>

This displays the tables vertically. How can I make them display horizontal?

Instead of outputting a new table for every single element, move the loop so that it outputs the elements inside a single table (each wrapped in their own <td>..</td> tags).

That works but if there are 20 items in the feed it makes the page really wide. How can I count them and start a new row after x amount?

You could maintain a counter variable inside the loop (e.g. increment it after each element) and use modulus logic to limit the number of elements per row, e.g.:

if($i % $num_per_row == 0) {
  // end previous row and start a new one
}

Sorry I don't know how to do that???

I just mean count how many elements you've outputted so far...

$i = 1;

foreach($foo as $bar) {
  // output elements here

  // increment counter
  $i++;
}

I am a newb here and I still don't understand.
This seems to give me the correct total but how do I tell it to break after so many?

$count= count($xml->Items->Item);

This sets the count variable at ten but I am not sure if that is helping me or not. I have no idea how to count how many have been outputted so far.

Thanks for the help.

I am getting closer. Here is the code I am using.

<?php 
foreach($xml->Foods->Food as $Food){ 
 { if (++$i > 4) { echo("<td>&nbsp;</td>");
 echo("</tr>");
  }
$title = $Food->Title ; 
?>

This works for the first four items and then the rest continue to display vertically.
