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();
	      }

	      $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");

	      $city = "'s Hertogenbosch";

	      /* this query will fail, cause we didn't escape $city */
	      if (!$maxdb->query("INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
		 printf("Error: %s
", $maxdb->sqlstate);
	      }

	      $city = $maxdb->real_escape_string($city);

	      /* this query with escaped $city will work */
	      if ($maxdb->query("INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
		 printf("%d Row inserted.
", $maxdb->affected_rows);
	      }

	      $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();
	      }

	      maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");

	      $city = "'s Hertogenbosch";

	      /* this query will fail, cause we didn't escape $city */
	      if (!maxdb_query($link, "INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
		 printf("Error: %s
", maxdb_sqlstate($link));
	      }

	      $city = maxdb_real_escape_string($link, $city);

	      /* this query with escaped $city will work */
	      if (maxdb_query($link, "INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
		 printf("%d Row inserted.
", maxdb_affected_rows($link));
	      }

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...>
       Error: 42000
       1 Row inserted.

		 /* close statement */
		 $stmt->close();
	      }

	      /* close connection */

		 maxdb_stmt_close($stmt);
	      }

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

       The above example will output something similar to:

       Error: -4004.
