Bug description: serialized object: data loss in some use case
Description:
------------
If i serialize a PHP object, then become some \0 characters in property's
field name. This cause some problems, where others using char* instead of
smart_str.
Example: If i try escape a serialized object's string with
pg_escape_string() then i give a truncated string, because the
PQescapeStringConn()/PQescapeString() terminate the processing at the \0
character.
Reproduce code:
---------------
class aClass
{
private $a;
public function __construct()
{
$this->a = 1;
}
}
$obj = new aClass();
$str = serialize($obj);
// gives: 'O:6:"aClass":1:{s:9:"#aClass#a";i:1;}'
// (i marked \0's places with a #)
echo $str;
$conn = pg_connect('...');
// gives: 'O:6:"aClass":1:{s:9:"'
echo pg_escape_string($conn, $str);
Expected result:
----------------
I think it would be better, if the serialize don't give \0. I think, it's
can not be problem, if serialize uses # or anything instead of \0.
Actual result:
--------------
See code.
