PHP MSSQL - 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 mssql_query() function, catch the returning object as a result set, and loop through the result with mssql_fetch_array() function in a while loop as shown in the following sample PHP script:

<?php
  $con = mssql_connect('LOCALHOST','sa','FYIcenter');
  mssql_select_db('FyiCenterData', $con);

  $sql = "SELECT id, url, time FROM fyi_links";
  $res = mssql_query($sql,$con);
  while ($row = mssql_fetch_array($res)) {
    print($row['id'].",".$row['url'].",".$row['time']."\n");
  }  
  mssql_free_result($res);

  mssql_close($con); 
?>

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

101,dev.fyicenter.com,
102,dba.fyicenter.com,
1101,moc.retneciyf.ved,
1102,moc.retneciyf.abd,
2101,dev.fyicenter.com,
2102,dba.fyicenter.com,

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