what does the \n do in my code?

it has just started appearing in my examples with no explanation. can anyone help a poor noob

eg print ("$users[$x]<br>\n");

thanks in advance

new line :)
What that snippet does it put a new line after an html line break, this just makes your source code look nicer - otherwise it could all be on one line

ah, thats the bit i have been after lol....wondered how to make a list!
