Status: No Feedback
Bug Type: PDO related
PHP Version: 5CVS-2007-09-07 (snap)
New Comment:
Adding the suggested parameter makes no different, the selected output
is still smaller than the input.
The following are the options I had added to the connection;
array( PDO::ATTR_EMULATE_PREPARES => false,
PDO::MYSQL_ATTR_INIT_COMMAND=>'SET CHARACTER SET utf8;',
PDO::MYSQL_ATTR_MAX_BUFFER_SIZE=>4194304 )
The octet_length in the mysql cli returns the incorrect value. So it's
the insert side that is having problems.
Adding PDO::MYSQL_ATTR_DIRECT_QUERY=>true to the constant list does not
help either.

I guess you're using emulated Prepared Statments, in that case PDO will
try to inject the binary data in the query, sett
PDO::ATT_EMULATE_PREPARES to false.
(it works with latin charsets since they ore 8byte charsets, whereas
utf-8 is multibyte)

Same problem on Debian Lenny (PHP 5.2.6-2).
I'm unable to insert LOB data if I'm using the utf-8 encoding (SET
CHARACTER SET utf8; ). Some caracters are converted to 0x3F.

PS.
If you remove the SET CHARACTER SET UTF-8 stuff, it works. I don't see
why that should screw up pdo sending in lobs though.

Description:
------------
See Ubuntu Bug 137960
I have duplicated this compiling on Mac OS X with the latest CVS
snapshot, so I think its not a Debian/Ubuntu packaging bug.
Reproduce code:
---------------
<?php
$imagesize = getimagesize('dm color logo copy.gif');
$fp = fopen('dm color logo copy.gif', 'rb');
/**
* On Linux/OS X, a 8262 byte image turns into 7966 bytes in the
database
* On Windows, it is stored with the correct size.
*/
$db = new PDO('mysql:host=localhost;dbname=play', 'db_username',
'db_password', array( PDO::MYSQL_ATTR_INIT_COMMAND=>'SET CHARACTER SET
utf8;', PDO::MYSQL_ATTR_MAX_BUFFER_SIZE=>4194304 ) );
$prepared = $db->prepare('INSERT INTO `files` (`type`,`data`) VALUES
(:type, :data)');
$prepared->bindParam(':type',$imagesize['mime'], PDO::PARAM_STR, 50);
$prepared->bindParam(':data', $fp, PDO::PARAM_LOB);
$prepared->execute();
$id = $db->lastInsertId();
$prepared = $db->prepare('SELECT `type`, `data` FROM `files` WHERE
`fileid` = :fileid');
$prepared->bindParam(':fileid',$id, PDO::PARAM_INT);
$prepared->execute();
$prepared->bindColumn(1, $type, PDO::PARAM_STR, 256);
$prepared->bindColumn(2, $lob, PDO::PARAM_LOB);
$prepared->fetch(PDO::FETCH_BOUND);
header("Content-Type: $type");
echo $lob;
?>
Expected result:
----------------
properly output image as on
http://cowsandmilk.homeip.net/pdolob/pdolobtest.php
Actual result:
--------------
image missing bytes as on http://cowsandmilk.net/pdolob/pdolobtest.php
(goes from 8262 bytes to 7966 bytes)
