Hello,

I'm curious on why this:

echo '<img src="' . $product["img"] . '" alt="' . $product["name"] . '">';

works, while this:

echo '<img src=" . $product['img'] . " alt=" . $product['name'] . ">';

does not. Everything is paired up nicely on the code that does not work. Why do we need the extra single quotes on the code that works?

Apologies if I'm going mad, but both lines of code appear to be identical!

echo '<img src="' . $product["img"] . ' " alt=" ' . $product["name"] . ' ">';
// output: <img scr="url/to/img.jpg" alt="alt text">

echo '<img src=" . $product['img'] . " alt=" . $product['name'] . ">';
// output: <img scr=url/to/img.jpg alt=alt text>

The challenge isn't passing with the second one because it is generating improper html. HTML attributes values have to be surrounded by quotes.

Are you sure you entered the code snippets correctly? On my screen, both code snippets have 6 paired up single-quote characters. I don't seen an 'extra' single quote on either.

You need the closing single quote on the first part of your string *'<img src=" *, The ending doublequote charaacter does not close it.
