for each question

Ok, I have searched the net for hours, but I couldn’t get an answer for my question.

If we use the for “each function” in php we can get a list of items like:
Jack
John
Adrian
Etc

But the first name a want to have bold so it looks like:
Jack
John
Adrian
Etc

Best way for me to do this, is to ad a class to the first name in the php code. But how do I do this? Cause the “for each” generates a list that is the same for eacht row (php/html code wise). So I only want the first name to be bold using a class (from a css) but all others not effected.

Thx
