>Alternative syntax for control structures</H1
><P
>&#13;    PHP offers an alternative syntax for some of its control
    structures; namely, <TT
CLASS="literal"
>if</TT
>,
    <TT
CLASS="literal"
>while</TT
>, <TT
CLASS="literal"
>for</TT
>,
    <TT
CLASS="literal"
>foreach</TT
>, and <TT
CLASS="literal"
>switch</TT
>.
    In each case, the basic form of the alternate syntax is to change
    the opening brace to a colon (:) and the closing brace to
    <TT
CLASS="literal"
>endif;</TT
>, <TT
CLASS="literal"
>endwhile;</TT
>,
    <TT
CLASS="literal"
>endfor;</TT
>, <TT
CLASS="literal"
>endforeach;</TT
>, or
    <TT
CLASS="literal"
>endswitch;</TT
>, respectively.

>&#13;    In the above example, the HTML block "A is equal to 5" is nested within an
    <TT
CLASS="literal"
>if</TT
> statement written in the alternative syntax.  The
    HTML block would be displayed only if $a is equal to 5.
   </P
><P
>&#13;    The alternative syntax applies to <TT
CLASS="literal"
>else</TT
> and
    <TT
CLASS="literal"
>elseif</TT
> as well.  The following is an
    <TT
CLASS="literal"
>if</TT
> structure with <TT
CLASS="literal"
>elseif</TT
> and
    <TT
CLASS="literal"
>else</TT
> in the alternative format:
