New Comment:
The PHP OCI8 bind lengths are bytes, as you noted. The underlying Oracle OCI C library documents
this appropriately "This size is always expected to be the size in bytes".
(http://docs.oracle.com/database/121/LNOCI/oci16rel003.htm#LNOCI17140)
The PHP OCI8 doc needs to have similar wording. There are no plans to allow PHP OCI8 specify the
size in characters.

Description:
------------
After migrating to UTF8, database provides two-way semantics for text data types: byte (for single
byte encodings is a synonim of char) and char.
http://docs.oracle.com/cd/B28359_01/server.111/b28318/datatype.htm#CNCPT012
Length field in oci_bind_by_name() function forcely expect byte data size.
For now we should update documentation noting it.
For future development, ma be it is reasonable to add a modifier to switch between char and byte
semantics.
SQL> CREATE TABLE EXAMPLE (
MESSAGE VARCHAR2(16 CHAR) NOT NULL
);
Oracle's client locale is:
NLS_LANG=RUSSIAN_RUSSIA.AL32UTF8
Test script:
---------------
<?php
require_once("../inc/conn.inc");
$conn = conn("UPO");
$var = "ÑеÑÑ-ÑеÑÑ";
$stid = oci_parse($conn, 'INSERT INTO EXAMPLE VALUES (:bv)');
oci_bind_by_name($stid, ':bv', $var, 9);
if (oci_execute($stid)) {
echo ("insert OK");
oci_free_statement($stid);
oci_close($conn);
}
else
echo ("insert failed");
?>
Expected result:
----------------
If client's locale is NLS_LANG=RUSSIAN_CIS.CL8ISO8859P5 properly encoded (translated from UTF8
back to ISO-8859-5) script works fine.
I expect the same for modern UTF8 locale.
Or at least proper description of issued function: what and how should be corrected.
Actual result:
--------------
If client is configured to use UTF8 locale, quoted script failes with ORA-01461 (can bind a LONG
value only for insert into a LONG column) error.
Originally it was find for binding output variables for call of PL/SQL procedure.
In that case the error message was ORA-06525: Length Mismatch for CHAR or RAW data
