php连接odbc数据源并保存与查询数据的方法

$connstr = "driver=microsoft access driver (*.mdb);dbq=".realpath("db.mdb");

$odbc_exec = odbc_exec($connid, "insert into tablename (name) values('name')");    
$query = odbc_do($connid, "select * from tablename ");   
$odbc_result_all = odbc_result_all($query);    
echo $odbc_result_all; 
//保存数据
$connstr = "driver=microsoft access driver (*.mdb);dbq=".realpath("db.mdb"); 
$connid = odbc_connect($connstr,"","",sql_cur_use_odbc);
$odbc_exec = odbc_exec($connid, "insert into t……")
//查询数据
