Bug #77067 [NEW]: Inserting a BLOB from a stream transforms it to a string
From: php at bohwaz dot net
Operating system: All
PHP version: 7.3.0RC4
Package: PDO SQLite
Bug Type: Bug
Bug description:Inserting a BLOB from a stream transforms it to a string
Description:
------------
If passing a stream as a parameter of PDOStatement::bindParam it is
transformed to a string which contains the stream contents.
For example this prevents reusing the stream handle to close it properly
or to truncate or change the file contents.
Test script:
---------------
<?php
$pdo = new PDO('sqlite::memory:');
$pdo->exec('CREATE TABLE test (a INTEGER, b BLOB);');
$fp = tmpfile();
fwrite($fp, 'Random stuff!');
fseek($fp, 0);
$stmt = $pdo->prepare('INSERT INTO test VALUES (?, ?);');
$stmt->bindValue(1, 42);
$stmt->bindParam(2, $fp, PDO::PARAM_LOB);
$stmt->execute();
var_dump(gettype($fp));
Expected result:
----------------
resource
Actual result:
--------------
string
