DB2_CLOSE(3)								 1							      DB2_CLOSE(3)

db2_close - Closes a database connection

SYNOPSIS

       bool db2_close (resource  $connection)

DESCRIPTION

	This function closes a DB2 client connection created with db2_connect(3) and returns the corresponding resources to the database server.

	If  you  attempt to close a persistent DB2 client connection created with db2_pconnect(3), the close request is ignored and the persistent
       DB2 client connection remains available for the next caller.

PARAMETERS

	      o $connection
		- Specifies an active DB2 client connection.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Closing a connection

	       The following example demonstrates a successful attempt to close a connection to an IBM DB2, Cloudscape, or Apache Derby database.

	      <?php
	      $conn = db2_connect('SAMPLE', 'db2inst1', 'ibmdb2');
	      $rc = db2_close($conn);
	      if ($rc) {
		  echo "Connection was successfully closed.";
	      }
	      ?>

	      The above example will output:

	      Connection was successfully closed.
