PHP echo variable and html together

I know this is the main php question, but I am having problems displaying variables inside the HTML echo. Below I am trying to achieve.

<?php
    $variable = 'testing';
    echo <span class="label-[variable]">[variable]</span>
?>

should be displayed:

<span class="label-testing">testing</span>

<?php

    echo <span class="label-[variable]">[variable]</span>
?>

Must be

<?php
    $variable = 'testing';
    echo '<span class="label-' . $variable .'">' . $variable . '</span>';
?>

If your HTML contains double quotes, you can wrap it in single quotes:

echo '<span class="label-' . $variable . '">' . $variable . '</span>';

Alternatively, you can do this inline by avoiding double quotes:

echo "<span class=\"label-$variable\">$variable</span>";

The use of double quotes also allows for special characters, such as \nand \t.

The documentation is your friend.
