PHP爆炸并放入数组

Question

我有这一行字符串

Fruits-banana|apple|orange:Food-fries|sausages:Desserts-ice cream|apple pie

的:(结肠)是主要议题隔板,并且|对于不同类型的子主题的分隔符.

我试图将它爆炸并将其放入数组中,我需要将结果显示在下拉菜单中: -

    Fruits
      banana
      apple
      orange
    Food
      fries 
      sausages

    $result=explode(":",$data);
     foreach($result as $res) {
      $sub_res[]=explode("-",$res);

     }


     foreach($sub_res as $sub) {
      //echo $sub[1]."<br>"; Over here, I can get the strings of [0]=>banana|apple|orange, [1]=>sausages|fries, 
        // I explode it again to get each items 
            $items[]=explode("|",$sub[1]);
      $mainCategory[]=$sub[0]; // This is ([0]=>Fruits, ]1]=>Food, [2]=>dessert
            // How do I assign the $items into respective categories?
    }

谢谢!

你可以做:

$result=explode(":",$data);
foreach($result as $res) {
        $sub = explode("-",$res);
        $mainCategory[$sub[0]] = explode("|",$sub[1]);
}
