Don't understand this part...

Hi!

Can you please help me understand this part:

<?php
public function getCombinedIngredients()
    {
      $ingredients = array();
      foreach ($this->recipes as $recipe) {
        foreach ($recipe->getIngredients() as $ing) {
          $item = $ing["item"];
          if (strpos($item, ",")) {
            $item = strstr($item, ",", true);
          }
          if (in_array($item."s", $ingredients)) {
            $item.="s";
          } else if (in_array(substr($item, 0, -1), $ingredients)) {
            $item = substr($item, 0, -1);
          }
          $ingredients[$item] = array(
            $ing["amount"],
            $ing["measure"]
          );
        }
      }
      return $ingredients;
    }

If at the end we add the "amount" and "measure" why it does not display it? Thanks for your help!

Can you provide the sample output array of $this->recipes and $recipe->getIngredients() ?
