Simple PHP switch case changing output... What am i doing wrong? - php

Question

Main Question:
Does an echo output differently inside a switch than on its own?
--
I don't think this is anything too involved, but it's certainly causing a little bit of headache for me!
To start with something simple, I'm able to show the Joomla full article image like this:
<img src="<?php echo htmlspecialchars($images->image_fulltext); ?>" />
I then wanted to expand this, and add a lightbox to the image, which turned into this:
<a href="<?php echo htmlspecialchars($images->image_fulltext); ?>" data-lightbox="image">
<img src="<?php echo htmlspecialchars($images->image_fulltext); ?>" />
</a>
The lightbox works fine.
However, then I only wanted this lightbox to apply to certain menu IDs (I have a News section in multiple languages, and so want to only apply the hyperlinks when certain pageIDs were being viewed).
I decided to make a switch (simple enough!)
<?php
$app = JFactory::getApplication();
$menuID = $app->getMenu()->getActive()->id;
switch ($menuID) {
case '168':
case '231':
echo
"<a href='".htmlspecialchars($images->image_fulltext)."' data-lightbox='image'>
<img src='".htmlspecialchars($images->image_fulltext)."' />
</a>";
break;
default:
echo
"<img src='".htmlspecialchars($images->image_fulltext)."' />";
break;
}
?>
The problem is that the switch is changing the output of src.
Outside of switch: /armouredshielding/images/news-events/website-screenshot.jpg
Inside switch: images/news-events/website-screenshot.jpg
surely this isn't the way switches work is it? It's still using an echo command, so the output should be exactly the same?
Any help is greatly appreciated!

I prefer something more like this:
$pagesToLight = array (168,231);
if(in_array($menuID, $pagesToLight)){
echo "<a href='".htmlspecialchars($images->image_fulltext)."' data-lightbox='image'>
<img src='".htmlspecialchars($images->image_fulltext)."' />
</a>";
} else {
echo "<img src='".htmlspecialchars($images->image_fulltext)."' />";
}
