Suite a l'indisponibilité du service lcsqa qu'utilisait le script perl,j'ai codé un nouveau script a partir des données du site prev'air.
Voici le script php qui se presente sous la forme d'une classe:

?>Pour executer le script un sipmle "php fichier.php" suffit.
Le script est parametrable de 2 facons:
-une premiere ou vous indiquez votre longitude et latitude (en haut du script) et cela calcule la station la plus proche
