Hi, I can’t code at all, my boyfriend is a PHP web dev and I want to write him some birthday code, a simple happy birthday with a link to a photo of us from my instagram. Sorry if this is super lame but it would be amazing if someone could help me
Thanks 
Then I would use html for it.

Play with that for a bit and see what you come up with.
PHP will require a server. While he would have that, it also needs to be accessed a certain way. HTML doesn’t need to be.
This outputs “Happy Birthday!”. If I knew the Instagram link I would have added it.
<?php
echo base64_decode('SGFwcHkgQmlydGhkYXkh');
