maxdb_fetch_row - Get a result row as an enumerated array

       Procedural style

SYNOPSIS

       mixed maxdb_fetch_row (resource	$result)

DESCRIPTION

       Object oriented style
       mixed maxdb_result::fetch_row (void  )

	Returns an array that corresponds to the fetched row, or NULL if there are no more rows.

       maxdb_fetch_row(3)  fetches  one  row  of data from the result set represented by $result and returns it as an enumerated array, where each
       column is stored in an array offset starting from 0 (zero). Each subsequent call to the maxdb_fetch_row(3) function will  return  the  next
       row within the result set, or FALSE if there are no more rows.

RETURN VALUES

       maxdb_fetch_row(3) returns an array that corresponds to the fetched row or NULL if there are no more rows in result set.

       Note

	      This function sets NULL fields to the PHP NULL value.

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, state FROM hotel.city ORDER by zip";

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

		 /* fetch enumerated array */
		 while ($row = $result->fetch_row()) {
		     printf ("%s (%s)
", $row[0], $row[1]);
		 }

		 /* free result set */
		 $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, state FROM hotel.city ORDER by zip";

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

		 /* fetch enumerated array */
		 while ($row = maxdb_fetch_row($result)) {
		     printf ("%s (%s)
", $row[0], $row[1]);
		 }

		 /* free result set */
		 maxdb_free_result($result);
	      }

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

       Example #2

	      Procedural style

	      maxdb_autocommit($link, FALSE);

	      maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
	      maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");

	      maxdb_query($link, "DROP TABLE temp.mycity");

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       0 rows in table mycity.
