EXAMPLES
       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      $query = "SELECT name, cno from hotel.customer ORDER BY name";

	      if ($result = $maxdb->query($query)) {

		 /* Get field information for column 'SurfaceArea' */
		 $finfo = $result->fetch_field_direct(1);

		 printf("Name:	   %s
", $finfo->name);
		 printf("Table:    %s
", $finfo->table);
		 printf("max. Len: %d
", $finfo->max_length);
		 printf("Flags:    %d
", $finfo->flags);
		 printf("Type:	   %d
", $finfo->type);

		 $result->close();
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      $query = "SELECT name, cno from hotel.customer ORDER BY name";

	      if ($result = maxdb_query($link, $query)) {

		 /* Get field information for column 'cno' */
		 $finfo = maxdb_fetch_field_direct($result, 1);

		 printf("Name:	   %s
", $finfo->name);
		 printf("Table:    %s
", $finfo->table);
		 printf("max. Len: %d
", $finfo->max_length);
		 printf("Flags:    %d
", $finfo->flags);
		 printf("Type:	   %d
", $finfo->type);

		 maxdb_free_result($result);
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Name:	 CNO
       Table:
       max. Len: 4
       Flags:	 -1
       Type:	 0
