at first, I'd like to point out that semicolon as a statement separator is not required before end of the php fragment and is supplied automatically during parsing. That's why the if-statements initiated above are evaluated independently of the rest of code and 'Hello' is always on output. It is equivalent to: <?php if (false); ?>Hello<?php ?> or <?php if (true); ?>Hello<?php ?> > <?php > if (false) > ?>Hello<?php > else > echo "Hi"; > > echo " World\n"; > ?> > For this reason the above fragment generates parse error because 'if' is evaluated separately and then 'else' is unexpected. If You want to interlard the php control blocks (in case of if, switch, for, etc. statements) You must use colon syntax as following: <?php if (false): ?>Hello<?php else: echo "Hi"; endif; //this is is the end of the if statement; its required when using colon syntax echo " World\n"; ?> Hope it helps, Mike -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
