<para>
|
|
For most errors, the parameter is the most appropriate resource
|
|
handle. For connection errors with <function>oci_connect</function>,
|
|
<function>oci_new_connect</function> or <function>oci_pconnect</function>,
|
|
do not pass a parameter. If no error is found, <function>oci_error</function>
|
|
returns &false;. <function>oci_error</function> returns the error as an
|
|
associative array. In this array, <literal>code</literal>
|
|
consists the oracle error code and <literal>message</literal>
|
|
the oracle error string.
|
|
</para>

<note>
|
|
<title>As of PHP 4.3</title>
|
|
<para>
|
|
<literal>offset</literal> and <literal>sqltext</literal> will
|
|
also be included in the return array to indicate the location
|
|
of the error and the original SQL text which caused it.

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