[FX.php List] A nagging question: Foreach

[Leo R. Lundgren]

If you have only one statement that should be run in the loop, you  
can do simply:

	foreach(..)
		statement;

But if you have two or more statements that should be run in the  
loop, you must enclose them either with { and } or the foreach ..  
endforeach;. How else can PHP tell what following lines you want to  
be part of the loop?

So for example:

	foreach(..) {
		statement;
		statement;
	}

	foreach(..):
		statement;
		statement;
	endforeach;

Note the lack of a colon in the first example, the use of {} in the  
second example, and the use of a colon and a semicolon in the third  
example.

Check the PHP manual under "Control Structures" for more information.
