PHP 7.2.0 Beta 1 Released


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

oci_set_client_identifierSets the client identifier


bool oci_set_client_identifier ( resource $connection , string $client_identifier )

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 'roundtrip' 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.

Elenco dei parametri


Un identificativo di connessione Oracle, restituito da oci_connect(), oci_pconnect(), o oci_new_connect().


User chosen string up to 64 bytes long.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.


Example #1 Setting the client identifier to the application user


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

// Tell Oracle who that user is

// The next roundtrip to the database will piggyback the identifier
$s oci_parse($c'select mydata from mytable');

// ...




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 which is all about using oci_set_client_identifier()
