Establishes a new connection to an Oracle server and logs on.

<para>

Unlike <function>oci_connect</function> and
|
|
<function>oci_pconnect</function>, <function>oci_new_connect</function>
|
|
does not cache connections and will always return a brand-new freshly
|
|
opened connection handle. This is useful if your application needs
|
|
transactional isolation between two sets of queries.

This optional parameter can either contain the name of the local

Oracle instance or the name of the entry in

If the not specified, PHP uses environment variables

determine the name of local Oracle instance and location of

<filename>tnsnames.ora</filename> accordingly.

This parameter is available since version 1.1 and accepts the
|
|
following values: <constant>OCI_DEFAULT</constant>,
|
|
<constant>OCI_SYSOPER</constant> and <constant>OCI_SYSDBA</constant>.
|
|
If either <constant>OCI_SYSOPER</constant> or
|
|
<constant>OCI_SYSDBA</constant> were specified, this function will try
|
|
to establish privileged connection using external credentials.
|
|
Privileged connections are disabled by default. To enable them you
|
|
need to set <link
|
|
linkend="ini.oci8.privileged_connect">oci8.privileged_connect</link>
|
|
to <literal>On</literal>.

If you're using PHP with Oracle Instant Client, you can use easy connect
|
|
naming method described here:
|
|
<ulink url="&url.oracle.oic.connect;">&url.oracle.oic.connect;</ulink>.
|
|
Basically this means you can specify "//db_host[:port]/database_name"
|
|
as database name. But if you want to use the old way of naming you
|
|
<emphasis>must</emphasis> set either <constant>ORACLE_HOME</constant> or
|
|
<constant>TNS_ADMIN</constant>.
|
|

|
<para>
|
|
In PHP versions before 5.0.0 you must use <function>ocinlogon</function> instead.
|
|
This name still can be used, it was left as alias of
|
|
<function>oci_new_connect</function> for downwards compatability.
|
|
This, however, is deprecated and not recommended.
