db2_pclose
DB2_PCLOSE(3) 1 DB2_PCLOSE(3)db2_pclose - Closes a persistent database connectionSYNOPSIS
bool db2_pclose (resource $resource)
DESCRIPTION
This function closes a DB2 client connection created with db2_pconnect(3) and returns the corresponding resources to the database server.
Note
This function is only available on i5/OS in response to i5/OS system administration requests.
If you have a persistent DB2 client connection created with db2_pconnect(3), you may use this function to close the connection. To avoid
substantial connection performance penalties, this function should only be used in rare cases when the persistent connection has become
unresponsive or the persistent connection will not be needed for a long period of time.
PARAMETERS
o $connection
- Specifies an active DB2 client connection.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Closing a persistent connection
The following example demonstrates a successful attempt to close a connection to an IBM DB2 i5/OS database.
<?php
$conn = db2_pconnect('', '', '');
$rc = db2_pclose($conn);
if ($rc) {
echo "Connection was successfully closed.";
}
?>
The above example will output:
Connection was successfully closed.
