Exemple de code permettant de cr\u00e9er et d’\u00e9crire dans un fichier en PHP. Un des cas courant de ce besoins est la cr\u00e9ation de fichiers de configuration. Le code suivant permet de cr\u00e9er le fichier \u00ab\u00a0config.db.php\u00a0\u00bb qui comme son nom l’indiquer contiendra les constantes PHP permettant la connexion \u00e0 la base de donn\u00e9es.<\/p>\n

Imaginons qu’il s’agit d’une partie d’un installeur de site. On demande de remplir les informations de connexion \u00e0 l’utilisateur dans un formulaire classique. Une fois soumis on contr\u00f4le les champs, on v\u00e9rifie que la connexion fonctionne et dans ce cas, on cr\u00e9er le fichier de configuration.<\/p>\n

Dans le code est utilis\u00e9 le tableau $fields sens\u00e9 contenir les informations envoy\u00e9 par le formulaire (et pr\u00e9alablement contr\u00f4l\u00e9)<\/p>\n
