Description:
------------
I'm using PostgreSQL (8.2.x) and am having a problem inserting
serialized data containing null characters (\0) into the database. I am
using prepared statements and the bindValue() method to bind the
serialized data as a PDO::PARAM_STR.
It's not obvious from the output below, but these serialized strings
contain null values because of the private variables.
I can't seem to find an existing bug for this; however, it surprises me
that no one has reported this before.
Reproduce code:
---------------
$pdo = new PDO('pgsql: dbname=testdb user=postgres');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$pdo->exec('DROP TABLE testtbl');
} catch (PDOException $x) { /* ignore */ }
$pdo->exec('CREATE TABLE testtbl (id integer not null, txtcol text)');
class MyClass {
private $var1;
function __construct($val) { $this->var1 = $val; }
}
$serialized = serialize(array('foo' => new MyClass('bar'), 'baz' => new
MyClass('bingo!')));
print "Serialized data: " . $serialized . PHP_EOL;
$stmt = $pdo->prepare('INSERT INTO testtbl (id, txtcol) VALUES (1,
?)');
$stmt->bindValue(1, $serialized, PDO::PARAM_STR);
$stmt->execute();
$stmt = $pdo->query('SELECT * FROM testtbl WHERE id = 1');
$row = $stmt->fetch();
print "From database: " . $row['txtcol'] . PHP_EOL;
Expected result:
----------------
Serialized data:
a:2:{s:3:"foo";O:7:"MyClass":1:{s:13:"MyClassvar1";s:3:"bar";}s:3:"baz";O:7:"MyClass":1:{s:13:"MyClassvar1";s:6:"bingo!";}}
>From database:
a:2:{s:3:"foo";O:7:"MyClass":1:{s:13:"MyClassvar1";s:3:"bar";}s:3:"baz";O:7:"MyClass":1:{s:13:"MyClassvar1";s:6:"bingo!";}}
Actual result:
--------------
Serialized data:
a:2:{s:3:"foo";O:7:"MyClass":1:{s:13:"MyClassvar1";s:3:"bar";}s:3:"baz";O:7:"MyClass":1:{s:13:"MyClassvar1";s:6:"bingo!";}}
>From database: a:2:{s:3:"foo";O:7:"MyClass":1:{s:13:"
