Automatically generate class files based on the fields in Mysql:
But you need to import:
Require_once./db/ez_sql_core.php;
Require_once./db/ez_sql_mysql.php;
Help Document: Http://jvmultimedia.com/docs/ezsql/ez_sql_help.htm
:
Core code:
Copy the Code code as follows:
Class db{

Initialization
Public Function __construct () {

Returns the database name so

}

return $databasename;
}
Returns the database name so

$i = 0;
$result = @mysql_list_tables ($databasename);
