Returns the last error found

Description

oci_error(?resource $connection_or_statement = null): array|false

Returns the last error found.

The function should be called immediately after an error occurs. Errors are cleared by a successful statement.

Parameters

connection_or_statement: For most errors, connection_or_statement is the resource handle that was passed to the failing function call. For connection errors with oci_connect(), oci_new_connect() or oci_pconnect() null should be passed.

Return Values

If no error is found, oci_error() returns false. Otherwise, oci_error() returns the error information as an associative array.

}
?>

Example #2 Displaying the Oracle error message after a parsing error

    print htmlentities($e['message']);
    print "\n<pre>\n";
