Description:
------------
Bug was reproduced on Windows 2000 + PHP 4.3.1 + Firebird 1.0(W2K) and
on RedHat Linux 9.0 + PHP 4.3.2 + Firebird 1.5 RC3(Linux).
If BLOB size > 64K actual size of data returned by ibase_blob_get
equals to Actual Size minus 64K.
Reproduce code:
---------------
while ($res = fetchRow($q)) {
$val = $res->BLOBDATA;
$blobinfo = ibase_blob_info($val);
$blobhndl = ibase_blob_open($val);
$image = ibase_blob_get($blobhndl, blobinfo[0]);
echo $blobinfo[0]."\n";
echo strlen($image)."\n";
ibase_blob_close($blobhndl);
}
Expected result:
----------------
Above script produces, for example, 50000 50000 if BLOBDATA size
50000.[OK]. But if BLOBDATA size more than 65535 bytes script producing
something like this:
65978 442
i.e. 442=65978-65536.
ibase_blob_echo($VAL) works right.
