Description:
------------
When i iterate a array that contains Objects asociated with a numeric key  foreach statement changes the type of the variable from object to string then i can't access to the object methods but i can acces to its attributes. 

Reproduce code:
---------------
foreach ($Resultados as $Clave=>$Objeto){
	if($Clave!="Count" ||$Clave!="LegislaturaRomano"){
printf("<td class='tddatosazul'>%s</td>",$Objeto->denomiCorta); //Access to the object attribute

printf("<td class='tddatosazul'>%s</td>",//access object's method here it fails
$Objeto->getTotalInicitivasDictaminadas());

...

Expected result:
----------------
Display the result of the method getTotalInicitivasDictaminadas it only adds two values

Actual result:
--------------
Fatal error: Call to a member function on a non-object
