Multi level for loop i PHP

Efter mange overvejelser har jeg lavet en logik, der passer perfekt til mit behov. Dataene bliver spredt korrekt i accordianen. Men accordian-panelerne er ikke kollapset som standard. Jeg stiller et nyt spørgsmål til det. Her er linket

 <?php 
            $fistForLoopEnds = false;
            $secondForLoopEnds = false;
            $thirdForLoopEnds = false;
            $fourthForLoopEnds = false;
             ?>
          <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
           <?php foreach ($this->data2['distinct'] as $key) { ?>

          <div class="panel panel-<?php if ($fistForLoopEnds != true) {
              echo "danger";
              $panelId = "headingOne";
              $accodianId = "collapseOne";
              $accordionExpanded = "true";
          } elseif ($fistForLoopEnds == true && $secondForLoopEnds != true) {
              echo "warning";
              $panelId = "headingTwo";
              $accodianId = "collapseTwo";
              $accordionExpanded = "false\" class=\"collapsed";
