>Alternative syntax for control structures</A

>&#13;    PHP offers an alternative syntax for some of its control
    structures; namely, <VAR
CLASS="literal"
>if</VAR
>,
    <VAR
CLASS="literal"
>while</VAR
>, <VAR
CLASS="literal"
>for</VAR
>,
    <VAR
CLASS="literal"
>foreach</VAR
>, and <VAR
CLASS="literal"
>switch</VAR
>.
    In each case, the basic form of the alternate syntax is to change
    the opening brace to a colon (:) and the closing brace to
    <VAR
CLASS="literal"
>endif;</VAR
>, <VAR
CLASS="literal"
>endwhile;</VAR
>,
    <VAR
CLASS="literal"
>endfor;</VAR
>, <VAR
CLASS="literal"
>endforeach;</VAR
>, or
    <VAR
CLASS="literal"
>endswitch;</VAR
>, respectively.

>&#13;    In the above example, the HTML block "A is equal to 5" is nested within an
    <VAR

    HTML block would be displayed only if <VAR
CLASS="varname"
