You obviously don't know any php and furthermore are not willing to open up a book and look anything up. The trim function (mentioned above) is one that removes leading and trailing spaces from a string. That is all. It has nothing to do with a loop or with output. Why are you into something this deep if you don't know anything about php or programming? As a professional programmer I find it ridiculous when people with no knowledge think they can just jump into it and hope someone can hold their hand for the next 2 months teaching them what they should already have tried to learn for themselves. Have fun. It's a learning process that can possibly give you a new set of knowledge that you may find invaluable. But - it takes work. Good bye
