PHP version: 5.2.12
PHP Bug Type: MySQLi related
Bug description: MySQLi_Result sets values before calling constructor
Description:
------------
MySQLi_Result::fetch_object sets properties before calling the
constructor, see BUG #49521
The behavior is similar to the one in BUG #49521 which has been fixed as
of PHP 5.2.12.
Note: It should be considered that this behavior may be not bug at all.
Calling the constructor BEFORE setting the properties (as done in BUG
#49521) leaves no possibility to work with the data at "construction time"
of the object.
Setting default properties could be done by assigning them in the
class-definition, but setting other properties depending on the loaded data
is hard to do, when this data is not yet available when the constructor is
called. This problem is even harder to solve, as no setters for the
properties are called, even if they are declared as private.
Reproduce code:
---------------
class Test
{
private
$myprivate = 0;
function __construct()
{
echo 'constructor called, $myprivate is ', $this->myprivate;
}
function __set ( $name, $value )
{
echo 'setting ', $name, ' to ', $value;
$this->{$name} = (int) $value;
}
}
$mysqli->query('SELECT 1 AS myprivate, 2 AS
mypublic')->fetch_object('Test');
Expected result:
----------------
If the same way to handle this bug as in BUG #49521 is considered:
constructor called, $myprivate is 0
setting mypublic to 2
object(Test)#6 (2) {
["myprivate:private"]=>
string(1) "1"
["mypublic"]=>
int(2)
}
But maybe the following behavior would make more sense if it should be
changed:
constructor called, $myprivate is 0
setting myprivate to 1
setting mypublic to 2
object(Test)#6 (2) {
["myprivate:private"]=>
int(1)
["mypublic"]=>
int(2)
}
Actual result:
--------------
setting mypublic to 2
constructor called, $myprivate is 1
object(Test)#6 (2) {
["myprivate:private"]=>
string(1) "1"
["mypublic"]=>
int(2)
}
