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();
	      }

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

	      $query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";

	      /* prepare statement */
	      if ($stmt = $maxdb->prepare($query)) {

		 /* Bind variable for placeholder */
		 $code = 'N%';
		 $stmt->bind_param("s", $code);

		 /* execute statement */
		 $stmt->execute();

		 printf("rows inserted: %d
", $stmt->affected_rows);

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

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

	      $query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";

	      /* prepare statement */
	      if ($stmt = maxdb_prepare($link, $query)) {

		 /* Bind variable for placeholder */
		 $code = 'N%';
		 maxdb_stmt_bind_param($stmt, "s", $code);

		 /* execute statement */
		 maxdb_stmt_execute($stmt);

		 printf("rows inserted: %d
", maxdb_stmt_affected_rows($stmt));

		 /* close statement */
		 maxdb_stmt_close($stmt);
	      }

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

       The above example will output something similar to:

       rows inserted: 4
