Résumé :
1. La vérification par SMS est utilisée pour enregistrer et modifier les mots de passe.
2. Pour des raisons de sécurité, vérification ajax frontale. Le backend effectue également la validation.
3. Le processus est raisonnable et facile à changer.
4. Fonctions complètes, y compris la connexion, l'enregistrement et la modification du mot de passe.

Ce qui précède est une introduction détaillée aux fonctions de connexion, d'enregistrement et de modification de mot de passe implémentées par PHP Pour plus de contenu connexe, veuillez faire attention au site Web chinois de PHP (www.php.cn) !
