Jak przechodzić między obiektami w php

Question

Nie jestem zbyt obeznany z obiektami, zazwyczaj konwertuję je na tablice za pomocą skryptu, ale pomyślałem, że nadszedł czas, aby się tego nauczyć, więc pytam, jak mogę przechodzić tablicę obiektów i wyciągnąć konkretne informacje, których potrzebuję, przykład tego, co jest zwracane, znajduje się poniżej.

Answer 1

Nie musisz ich konwertować na nic.

pętla foreach będzie działać dobrze ze sobą w następujący sposób ogólna:

foreach ($objects as $obj) { 
    echo $obj->property; 
} 

na wewnętrznej obiektu to będzie działać:

foreach ($objects as $obj){ 
     echo $obj->user->description; 
}
