Newline in PHP email

I've tried everything I can personally think of to create a new line in my email being sent from php. "\n", "\r", "<br>" all end up being part of the email text rather than new lines. Anyone know what the issue is? Here's the part of the script that sends the message:

Nevermind...I just figured it out. It's because I was using single quotes rather than double quotes in my foreach statement.

Why is it I get stuck on something for 2 days, and then post here and figure it out in seconds? I should post on here more often hahaha.

I learn quicker under public scrutiny too. I think the pressure of looking like a moron makes us forget the distracting elements of our lives and focus on the task at hand.

Also, it's a pretty common thing for people to find their own bugs when explaining a problem to others. Much of it is because when you're examining your own code, you're operating with a bunch of assumptions that cause you to overlook or miss things. When you need to explain something to someone else, you drop the assumptions and end up seeing the issue yourself.

Totally agree spork - unfortunately the rubber ducky debugging method hasn't worked for me. Apparently needs to be a real person for some reason. Even someone who has absolutely no idea what I'm talking about. Seems to work well for me nearly every time.
