>Alternative syntax for control structures</A

><P
> 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.

> In the above example, the HTML block "A = 5" is nested within an
<TT

The HTML block would be displayed only if $a is equal to 5.

<TT

<TT

>if</TT
