<?php

mysql_query($sql) or die(mysql_errorB[/B]);

new to this php stuff. Find the syntax difficult to follow sometimes.
For instance, in the book I have the author refers to the echo() function. Then he goes on to use echo without the () ????????

Read the manual and it'll tell you echo isn't a function, it's a 'construct'. How lovely for all. Basically you can use it without the backets and the code looks damn nicer for it. What does my head in is seeing people using HTTP_SERVER_VARS_POST_GET and all that tripe, but I am new to this cooking pot of php funnery.
