From manual page: http://www.php.net/function.sqlsrv-num-fields
---
I believe that there is an error in the documentation page - one two many { characters in the example ...

I think that it should be ....

  // Example of sqlsrv_num_fields
  $sql = "SELECT * FROM Table_1";
  $query = sqlsrv_query($conn, $sql);
  if( $query === false) { die( print_r( sqlsrv_errors(), true)); }
  $numFields = sqlsrv_num_fields( $query );
  while( sqlsrv_fetch( $stmt )) {    
    for($i = 0; $i < $numFields; $i++) {   // Iterate through the fields of each row.
      echo sqlsrv_get_field($stmt, $i)." ";
      }
    echo "<br />";
    }
