db2_conn_error - Returns a string containing the SQLSTATE returned by the last connection attempt

SYNOPSIS
       string db2_conn_error ([resource  $connection])

DESCRIPTION
       db2_conn_error(3)  returns  an  SQLSTATE  value representing the reason the last attempt to connect to a database failed. As db2_connect(3)
       returns FALSE in the event of a failed connection attempt, you do not pass any parameters to db2_conn_error(3)  to  retrieve  the  SQLSTATE
       value.

	If,  however, the connection was successful but becomes invalid over time, you can pass the $connection parameter to retrieve the SQLSTATE
       value for a specific connection.

	To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line  Processor  prompt:  db2  '?	$sqlstate-
       value'. You can also call db2_conn_errormsg(3) to retrieve an explicit error message and the associated SQLCODE value.

PARAMETERS
	      o $connection
		- A connection resource associated with a connection that initially succeeded, but which over time became invalid.

RETURN VALUES
	Returns  the  SQLSTATE	value resulting from a failed connection attempt. Returns an empty string if there is no error associated with the
       last connection attempt.

EXAMPLES
       Example #1

	      Retrieving an SQLSTATE value for a failed connection attempt

	       The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect(3).

	      <?php
	      $conn = db2_connect('badname', 'baduser', 'badpassword');
	      if (!$conn) {
		  print "SQLSTATE value: " . db2_conn_error();
	      }
	      ?>

	      The above example will output:

	      SQLSTATE value: 08001
