<title>Oracle 8 functions</title>
<titleabbrev>OCI8</titleabbrev>
<partintro>
<simpara>
These functions allow you to access Oracle8 and Oracle7 databases. It
uses the Oracle8 Call-Interface (OCI8). You will need the Oracle8 client
libraries to use this extension.

<para>
This extension is more flexible than the standard Oracle
extension. It supports binding of global and local PHP variables
to Oracle placeholders, has full LOB, FILE and ROWID support
and allows you to use user-supplied define variables.
</simpara>
</para>
<para>
Before using this extension, make sure that you have set up your
oracle environment variables properly for the Oracle user, as well
as your web daemon user. The variables you might need to set are as
follows:
<itemizedlist>
<listitem>
<simpara>
ORACLE_HOME
</simpara>
</listitem>
<listitem>
<simpara>
ORACLE_SID
</simpara>
</listitem>
<listitem>
<simpara>
LD_PRELOAD
</simpara>
</listitem>
<listitem>
<simpara>
LD_LIBRARY_PATH
</simpara>
</listitem>
<listitem>
<simpara>
NLS_LANG
</simpara>
</listitem>
<listitem>
<simpara>
ORA_NLS33
</simpara>
</listitem>
</itemizedlist>
</para>
<para>
After setting up the environment variables for your webserver user,
be sure to also add the webserver user (nobody, www) to the oracle
group.

You can easily access stored procedures in the same way as you
would from the commands line.
<example>
<title>Using Stored Procedures</title>
<programlisting role="php">
&lt;?php
// by webmaster@remoterealty.com
$sth = OCIParse ( $dbh, "begin sp_newaddress( :address_id, '$firstname',
'$lastname', '$company', '$address1', '$address2', '$city', '$state',
'$postalcode', '$country', :error_code );end;" );
// This calls stored procedure sp_newaddress, with :address_id being an
// in/out variable and :error_code being an out variable.
// Then you do the binding:
OCIBindByName ( $sth, ":address_id", $addr_id, 10 );
OCIBindByName ( $sth, ":error_code", $errorcode, 10 );
OCIExecute ( $sth );
