You need to apply some basic common sense here. Just look at your code:

$mail->addStringAttachment(file_get_contents($url), 'img.png');
$url = "https://www.pexels.com/photo/woman-wearing-black-crew-neck-shirt-and-blue-denim-shorts-911575/";

1. You're setting the URL after you're trying to use it.
2. The URL does not link to an image.

Doing this interactively is a bad idea anyway - it's very slow.
