After the third step, we will call this class in the new PHP file, and instantiate the class:

<?phpinclude_once "sql.php";//Import class file//Use directly require the file, then instantiate: $SqlDB = new MySQLdb ("localhost", "root", "root", "ABCD $sql = "SELECT * from t_table WHERE 1"; $result = $SqlDB->query ($sql);//Query $rs = $SqlDB->getrows ($result);//get record set $ num = $SqlDB->getrowsnum ($result);//Get Record count//... The rest of the operation is the loop value, for ($i =0; $i < $num; $i + +) {echo "Sid:". $rs [$i] [SID]). " <br> "; echo" AA: ". ($rs [$i] ["AA"]). " <br> "; echo" BBC: ". ($rs [$i] [BBC]].
