Sie verwenden eine nicht überwachte, unsichere und lange veraltete Datenbank-API. Hör jetzt auf. Alternativen wie PDO gibt es seit mehr als zehn Jahren. Siehe http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php – miken32
@ miken32 In anderen Worten, es ist "veraltet" und nicht mehr unterstützt. –
ha ok sir, ... können Sie meinen Fehler erkennen Sir, bitte –
