Add comma to all valules except the last one?

PHP
1

Can anyone help me to to get this show like this:

value1, value2, value3

I mean not to add comma after the last value?

$explode = explode(", ",$fortag['tags']);
            $tagspostbit = "<div class='systemtag'>";
            $counttag = 0;
            foreach($explode as $tag)
            {
                $tagspostbit .= "<a href=\"tags/".$tag.".html\">".$tag."</a>, ";
                ++$counttag;
            }
            $tagspostbit .= "</div>";

You’re using the explode function already. implode does the opposite. Exactly what you want: http://php.net/function.implode

Instead of concatenating your tags into a string, add them to an array and use implode() to join them into a string at the end:

$explode = explode(", ", $fortag['tags']);
$counttag = 0;

$links = array();
foreach ($explode as $tag) {
    $links[] = "<a href=\"tags/$tag.html\">$tag</a>";
    ++$counttag;
}

$tagspostbit = '<div class="systemtag">' . implode(', ', $links) . '</div>';

I think what you’re looking for is to use rtrim() before the

$tagspostbit .= "</div>";

And implode would work fine too. Up to you.

Though I’m a bit confused as to how that would look as link text
