Updating existing rows in a table requires to run the UPDATE statement with a WHERE clause to identify the row. The following sample script updates one row with two new values:

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

  $sql = "UPDATE fyi_links SET notes='Nice site.', counts=8"
    . " WHERE id = 102";
  $res = mssql_query($sql,$con);
  if (!$res) {
    print("SQL statement failed with error:\n");
    print("   ".mssql_get_last_message()."\n");
  } else {
    $number_of_rows = mssql_rows_affected($con);
    print("$number_of_rows rows updated.\n");
  }

  mssql_close($con); 
?>

If you run this script, you will get something like this:

1 rows updated.
