Question

Is it possible to add a break tag after every record, but not the last record?

Here’s my partial code:

if($db->num_rows($query) > 0)
{       
    while($listing = $db->fetch_array($query))
    {
        eval("\$page .= \"".$templates->get("page_template")."\";");
    }
}

Kind regards.

First of all: please don’t use eval, there’s no benefit to it in this situation and it poses a huge security risk. Second: the theory of “every item but the last” isn’t that hard, as you’ve already got the total number. Something like this may work:

<?php
if($db->num_rows($query) > 0)
{
    $count = 0;
    while($listing = $db->fetch_array($query))
    {
        $page .= $templates->get("page_template");
        if( ++$count !== $db->num_rows( $query ) ) {
            // add break tag.
        }
    }
}

As an alternative (and a cleaner solution), you might want to implode an array of content:

<?php
while( $listing = $db->fetch_array( $query ) ) {
    $pages[] = $templates->get( 'page_template' );
}
$page = implode( 'break-tag', $pages );
