Syntaxes alternatives

PHP propose une syntaxe alternative pour certaines de ses structures de contrôle : if, while, for, foreach, et switch. Dans chaque cas, la forme de base de la syntaxe alternative est de changer l'accolade d'ouverture par un deux-points (:) et l'accolade de fermeture par endif;, endwhile;, endfor;, endforeach;, ou endswitch;.
