4. Example

Please refers to PHP manual for ODBC functions. Here is my example code odbc.php3: (Note that odbc_num_rows() will not return anything, so you must repeately call odbc_fetch_row() to get that number.)

<?
/* some environment variables, you can test to comment them out to see
 * if things still work.

putenv("UDBCINI=/etc/udbc.ini");
putenv("ODBCINI=/root/.odbc.ini");
putenv("DebugFile=/tmp/udbc.out");      // debug trace output

$sql="SELECT * FROM titles";

        if($result_id=odbc_do($conn_id, $sql)) {

                        if($num_fields>0){
                                echo "Number of fields:

                        }else{
