Bonjour
Après tests de ma gestion perso ( avec Redis ) de sessions en PHP sur mon ordi en local, la fonction session_start() ne marche pas.
Message d'erreur "PHP message: PHP Warning: session_start(): Failed to read session data: user (path: /var/lib/php/session) in /var/www/html/php/config/sessions_handler.php on line 292
Sur le php.ini, le session_handler est à user.
Je ne sais pas où çà bugue.
Le session.serialize est à php_serialize.
Merci beaucoup de votre aide.
