How to place an funktion in an echo?

Question

I've searched for this for a while (also SO), but I just don't get it. I want to place an echo <?php echo get_tag_link($tag_id); ?> within an echo:

<?php
    $posttags = get_the_tags();
    $count=0;
    if ($posttags) {
        foreach($posttags as $tag) {
        $count++;
            if (1 == $count) {
                echo '<span class="tags"><a href="<?php echo get_tag_link($tag_id); ?>">';
                echo $tag->name . ' ';
                echo '</a></span>';
            }
        }
    }
?>

But clearly this is wrong..

you're already in PHP `` and error reporting http://php.net/manual/en/function.error-reporting.php would have helped you find that syntax error. So, why an "echo in an echo"?! — Funk Forty Niner, Dec 03 '15 at 14:36

You have to change the row to:

echo '<span class="tags"><a href="' . get_tag_link($tag_id) . '">';

You're already working within a PHP block so you don't need the <?php ?>

Similarly you're already echoing a string so the echo is also not needed.

What you're looking for is concatenation

Like this:

echo '<span class="tags"><a href="' . get_tag_link($tag_id) . '">';
