php conditionals?

am 15.09.2010 05:48:35 von stao

Hi,

I saw php usage like below somewhere. I kind of wonder why the page does
not display anything. in my understanding, php only interprets what is
inside . Since the form is outside of any php tags, the form
should be displayed?

Thank you for any helps.

if (0)

{

?>

}

?>

http://www.php.net/manual/en/language.types.boolean.php#lang uage.types.boole
an.casting
0 is interpreted as false. Thus the condition is not satisfied. The form
will never be shown.

Tommy

The

tag is being rendered between the { and } tags inside PHP tags
related to the conditional statement, so if the conditional statement isn't
true, even static HTML inbetween them won't show up.

Stay well
