oci_set_client_identifier

(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)

oci_set_client_identifierSets the client identifier

Descrizione

oci_set_client_identifier(resource $connection, string $client_id): bool

Sets the client identifier used by various database components to identify lightweight application users who authenticate as the same database user.

The client identifier is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.

The identifier can subsequently be queried, for example with SELECT SYS_CONTEXT('USERENV','CLIENT_IDENTIFIER') FROM DUAL. Database administration views such as V$SESSION will also contain the value. It can be used with DBMS_MONITOR.CLIENT_ID_TRACE_ENABLE for tracing and can also be used for auditing.

The value may be retained across page requests that use the same persistent connection.

Esempi

Example #1 Setting the client identifier to the application user

<?php

// Find the application user's login name
session_start();
$un = my_validate_session($_SESSION['username']);
$c = oci_connect('myschema', 'welcome', 'localhost/XE');

// Tell Oracle who that user is
oci_set_client_identifier($c, $un);

// The next round-trip to the database will piggyback the identifier
$s = oci_parse($c, 'select mydata from mytable');
oci_execute($s);

// ...

?>

Note

Attenzione

Attenzione ai roundtrip

Alcune funzioni OCI8 causano roundtrip. I roudntrip verso il database possono non verificarsi con le query quando il caching dei risultati รจ abilitato.

There's an article "PHP Web Auditing, Authorization and Monitoring with Oracle Database" at www.oracle.com/technetwork/articles/dsl/php-web-auditing-171451.html which is all about using oci_set_client_identifier()
