How to dynamically add to object array? - php

Question

So like when working with mysql_fetch_object(), how do you do things like this:
$array = array();
while($row = mysql_fetch_object($result))
{
$array[] = $row;
}
How do you accomplish that with objects instead of an array? Like,
$object = new stdClass;
while($row = mysql_fetch_object($result))
{
$object[] = $row;
}
Is there a way to do this without a lot of ugly typecasting?

Answer 1

The first method is correct,
it should assign all the objects into $array,
like an array,
you can access via
$arr[0]->$COLUMN ...
I bet you are not referring to this :-
$object = new stdClass;
while($row = mysql_fetch_object($result))
{
$props = "object_{$cnt}";
$object->$props = $row;
++$cnt;
}
The second method is assign each object into property of $object,
and you can assign the property as :-
$object->object_0->$COLUMN ...

Answer 2

Other languages (like C++, C# and Java) support "generics" so you don't have to do "a lot of ugly typecasting". PHP does't - hence the general need for a cast.
But in your case ... if "$row" starts out as an object when you put it into the array ... don't you get the same object back when you de-reference the array?

Answer 3

$object = array();
while($row = mysql_fetch_object($result))
{
$object[] = $row;
}
$object = new stdClass($object);
or
class myClass{
private $counter = 0;
public function add($row){
$count = $counter++;
$this->$count = $row;
}
}
$object = new myClass();
while($row = mysql_fetch_object($result))
{
$object->add($row);
}
or
class myClass implements ArrayAccess{
private $counter = 0;
public function offsetSet($offset, $value) {
if (is_null($offset)) {
$count = $counter++;
$this->$count = $value;
} else {
$this->$offset = $value;
}
}
public function offsetExists($offset) {
return isset($this->$offset);
}
public function offsetUnset($offset) {
unset($this->$offset);
}
public function offsetGet($offset) {
return isset($this->$offset) ? $this->$offset : null;
}
}
$object = new myClass();
while($row = mysql_fetch_object($result))
{
$object[] = $row;
}
