	      <?php
	      // Connect to MSSQL and select the database
	      mssql_connect('MANGOSQLEXPRESS', 'sa', 'phpfi');
	      mssql_select_db('php');

	      // Print the field length
	      echo 'The field 'age' has a data length of ' . mssql_field_length($query, 1);

NOTES
       Note

	      Note to Windows Users

	       Due to a limitation in the underlying API used by PHP (MS DBLib C API), the length of VARCHAR fields is limited to 255. If you need
	      to store more data, use a TEXT field instead.
