UTF8 requires 2 bytes per character.
Your database can store only 2 bytes (because it's ISO8859), but you're
trying to put 4 and receive the expected error.
Not PHP problem.

I made a mistake writing the actual result, it is obviously :
(array[0]->MYFIELD === 'é') === true
(array[0]->MYFIELD === 'éa') === false
Sorry for the typo.

Description:
------------
Hello,
While configured in UTF8 mode (eg with the connection string
allRequiredInfos;charset=UTF8), when we try to get a VARCHAR2 field
limited to X chars, PDO is assuming accents (éàè...) are 2 letters
length) and then generates a warning if our content is X chars length
(with accents) and truncates the end of the field.
Warning: PDOStatement::fetchAll()
[scriptAdr/function.PDOStatement-fetchAll]: column 0 data was too large
for buffer and was truncated to fit it in /scriptPath.class.php on line
73
We tryed to activate mbstring extension, to use func_overload=4 with no
success (the database itself is in ISO-8859-1).
If we try not to communicate with the database in UTF8, accents are
just ignored (é becomes e, ...) even with correct session parameters.
Reproduce code:
---------------
Considering the table
MYTABLE {
MYFIELD VARCHAR2(2);
}
with one record :
MyField
--------
éa
$pdo = new PDO ('pdo_oci:dbname=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
)
(CONNECT_DATA =
(SID = mysid)
)
);charset=UTF8', 'myLogin', 'myPassword');
$stmt = $pdo->doQuery ('select MYFIELD from MYTABLE');
$stmt->fetchAll (); //warning
Expected result:
----------------
(array[0]->MYFIELD === 'éa') === true;
Actual result:
--------------
(array[0]->MYFIELD === 'é') === true
(array[0]->MYFIELD === 'éa') === true
