PHPFORMYSQL code generation assistant (automatically generates class files based on Mysql fields ). The class file is automatically generated based on the fields in Mysql, but the class file needs to be imported: require_once.dbez_ SQL _core.php; require_once.dbez_ SQL _mysql.php; help document: jvmultimedia.com automatically generates class files according:

But you need to import:

Require_once./db/ez_ SQL _core.php;
Require_once./db/ez_ SQL _mysql.php;
