OCI_CLOSE(3)OCI_CLOSE(3)oci_close - Closes an Oracle connectionSYNOPSIS
bool oci_close (resource $connection)
DESCRIPTION
Unsets $connection. The underlying database connection is closed if no other resources are using it and if it was created with oci_con-
nect(3) or oci_new_connect(3).
It is recommended to close connections that are no longer needed because this makes database resources available for other users.
PARAMETERS
o $connection
- An Oracle connection identifier returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Closing a connection
Resources associated with a connection should be closed to ensure the underlying database connection is properly terminated and the
database resources are released.
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT * FROM departments');
$r = oci_execute($stid);
oci_fetch_all($stid, $res);
var_dump($res);
// Free the statement identifier when closing the connection
oci_free_statement($stid);
oci_close($conn);
?>
Example #2
Database connections are not closed until all references are closed
The internal refcount of a connection identifier must be zero before the underlying connection to the database is closed.
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT * FROM departments'); // this increases the refcount on $conn
oci_execute($stid);
oci_fetch_all($stid, $res);
var_dump($res);
oci_close($conn);
// $conn is no longer usable in the script but the underlying database
// connection is still held open until $stid is freed.
var_dump($conn); // prints NULL
// While PHP sleeps, querying the Oracle V$SESSION view in a
// terminal window will show that the database user is still connected.
sleep(10);
// When $stid is freed, the database connection is physically closed
oci_free_statement($stid);
// While PHP sleeps, querying the Oracle V$SESSION view in a
// terminal window will show that the database user has disconnected.
sleep(10);
?>
Example #3
Closing a connection opened more than once
When database credentials are reused, both connections must be closed before the underlying database connection is closed.
<?php
$conn1 = oci_connect('hr', 'welcome', 'localhost/XE');
// Using the same credentials reuses the same underlying database connection
// Any uncommitted changes done on $conn1 will be visible in $conn2
$conn2 = oci_connect('hr', 'welcome', 'localhost/XE');
// While PHP sleeps, querying the Oracle V$SESSION view in a
// terminal window will show that only one database user is connected.
sleep(10);
oci_close($conn1); // doesn't close the underlying database connection
var_dump($conn1); // prints NULL because the variable $conn1 is no longer usable
var_dump($conn2); // displays that $conn2 is still a valid connection resource
?>
Example #4
Connections are closed when variables go out of scope
When all variables referencing a connection go out of scope and are freed by PHP, a rollback occurs (if necessary) and the underly-
ing connection to the database is closed.
<?php
function myfunc() {
$conn = oci_connect('hr', 'hrpwd', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'UPDATE mytab SET id = 100');
oci_execute($stid, OCI_NO_AUTO_COMMIT);
return "Finished";
}
$r = myfunc();
// At this point a rollback occurred and the underlying database connection was released.
print $r; // displays the function return value "Finished"
?>
NOTES
Note
Variables that have a dependency on the connection identifier, such as statement identifiers returned by oci_parse(3), must also be
freed before the underlying database connection is closed.
Note
Prior to version PHP 5.1.2 (PECL OCI8 1.1) oci_close(3) was a no-op. In more recent versions it correctly closes the Oracle connec-
tion. Use oci8.old_oci_close_semantics option to restore old behavior of this function.
Note
The oci_close(3) function does not close the underlying database connections created with oci_pconnect(3).
