Derzeit erstellen wir ein Projekt über das Blockieren von Webseiten und ich habe nur ein paar Fragen über PHP und wie phpmyadmin auf bestimmte Aktionen reagiert. Ich benutze wampserver signup.php offenbar zeigt keine Fehler bei der Eingabe eines neuen Kontos, der Benutzername und das Passwort soll in der Datenbank gespeichert werden. Hier ist es:MySQL arbeitet nicht auf localhost

PS. Möglicherweise muss ich auch andere Codes hochladen, aber ich bin mir nicht sicher, was es ist.
Haben Sie in den Fehlerprotokollen gesucht? –
PhpMyAdmin ist nicht die Datenbank. MySQL ist die Datenbank. –
Dies kann ein größeres Problem sein als nur PHP funktioniert nicht, aber stellen Sie sicher, dass es in XAMPP nicht abgestürzt ist (was ich vermute, dass Sie verwenden) - wir brauchen mehr Informationen :-) – Jek
