       Procedural style

SYNOPSIS

       string maxdb_error (resource  $link)

DESCRIPTION

       Object oriented style
       string$maxdb->error ()

	The maxdb_error(3) function is identical to the corresponding maxdb_errno(3) function in every way, except instead of returning an integer
       error code the maxdb_error(3) function will return a string representation of the last error to occur for the  database	connection  repre-
       sented by the $link parameter. If no error has occurred, this function will return an empty string.

RETURN VALUES

	A string that describes the error. An empty string if no error occurred.

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();
	      }

	      if (!$maxdb->query("SELECT xxx FROM hotel.city")) {
		 printf("Errormessage: %s
", $maxdb->error);
	      }

	      /* 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();
	      }

	      if (!maxdb_query($link, "SELECT xxx FROM hotel.city")) {
		 printf("Errormessgae: %s
", maxdb_error($link));
	      }

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

       The above example will output something similar to:

       PHP Warning:  maxdb_query(): -4005 POS(8) Unknown column name:XXX [42000]
       Errormessgae: POS(8) Unknown column name:XXX

		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();

	      /* check if server is alive */
	      if ($maxdb->ping()) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", $maxdb->error);
	      }

	      /* close connection */

		 exit();
	      }

	      /* check if server is alive */
	      if (maxdb_ping($link)) {
