conversion asp vers php

bonjour à tous et merci d'avance
j'ai un petit fichier en asp que je veux convertir en php (car je crois que chez free asp n'est pas possible) ;
j'ai trouvé un logiciel de conversion et j'ai effectué la conversion et cela ne fonctionne pas .
est ce que quelqu'un peut se pencher sur la syntaxe de la ligne php mise en évidence et l'équivalent asp en dessous ?
j'ai mis en évidence dans les 2 versions une ligne qui ne va pas dans le code php : merci de me corriger cette ligne

Code:
