Be aware of a reference to another reference. It is probably bad practice to even do that.
<?php
class Obj1 { public $name = 'Obj1'; }
class Obj2 { public $name = 'Obj2'; }
$objects = [];
$toLoad = [ 'Obj1', 'Obj2' ];
foreach( $toLoad as $i => $obj )
{
$ref = new $obj();
$objects[$i] =& $ref; // a reference to a reference
// $objects[$i] = $ref; // that would work
}
echo $objects[0]->name;
// outputs 'Obj2' !
?>
