>&#13;    O PHP oferece uma sintaxe alternativa para algumas das suas estruturas
    de controle: <TT
CLASS="literal"
>if</TT
>,
    <TT
CLASS="literal"
>while</TT
>, <TT
CLASS="literal"
>for</TT
>,
    <TT
CLASS="literal"
>foreach</TT
> e <TT
CLASS="literal"
>switch</TT
>.
    Em cada caso, a forma básica da sintaxe alternativa é mudar
    o sinal de abertura para dois-pontos (:) e o sinal de fechamento para
    <TT
CLASS="literal"
>endif;</TT
>, <TT
CLASS="literal"
>endwhile;</TT
>,
    <TT
CLASS="literal"
>endfor;</TT
>, <TT
CLASS="literal"
>endforeach;</TT
> ou
    <TT
CLASS="literal"
>endswitch;</TT
>, respectivamente.

>&#13;    No exemplo acima, o bloco HTML "A é igual a 5" está aninhado dentro de uma instrução
    <TT
CLASS="literal"
>if</TT

    O bloco HTML será mostrado somente se <CODE
CLASS="varname"
>$a</CODE
> é igual a 5.

>&#13;    A sintaxe alternativa se aplica a <TT

    <TT
CLASS="literal"
>if</TT
