PHP ODBC - How To Loop through Returning Rows?

The best way to query tables and loop through returning rows is to run a SELECT statement with the odbc_exec() function, catch the returning object as a result set, and loop through the result with odbc_fetch_array() function in a while loop as shown in the following sample PHP script:

  $con = odbc_connect('FYI_SQL_SERVER','sa','FYIcenter');

  $sql = "SELECT id, url, time FROM fyi_links";
  $res = odbc_exec($con, $sql);
  while ($row = odbc_fetch_array($res)) {


Using odbc_fetch_array() is better than other fetch functions, because it allows you to access field values by field names. If you run this script, you will see all rows from the fyi_links table are printed on the screen:


Don't forget to call odbc_free_result($res). It is important to free up result set objects as soon as you are done with them.
