[SOLVED] Foreach problem - simple question

[JSHINER]

<?php foreach($page['categories'] as $cat) { echo '<a href="page.php?category=', $cat['id_cat'], '">', $cat['name'], '</a> | '; } ?>

 

Displays "Category 1 | Category 2 | Category 3 |"

 

How can I get rid of that last " | "

Throw an if() statement in there to check if it is Category 3.  If it is, do not echo the |, if it is not, echo the |.

I need it to work if there's 3 categories of 100. Just need it to not display on the last one.

You could check to find the total number of Categories and then use the if() statement.

Maybe this works for you:

 

<?php 
foreach($page['categories'] as $cat) $x[] = '<a href="page.php?category=' . $cat['id_cat'] . '">' . $cat['name'] . '</a>';
echo join(' | ', $x);
?>
