Решение №1 - не рекомендуемое, для разминки с циклом for

 for ($n = 0; $n < count($obj->regions); $n++) {
    for ($j = 0; $j < count($obj->regions[$n]->lines); $j++) {
       for ($i = 0; $i < count($obj->regions[$n]->lines[$j]->words); $i++) {
          echo $obj->regions[$n]->lines[$j]->words[$i]->text." ";
       }
    }
 }

Решение №2 - рекомендуемое

foreach($obj->regions as $regions) {
     foreach($regions->lines as $lines) {
            foreach($lines->words as $words) {
                  echo $words->text . " ";
            }
     }
}
