PHP爆炸并投入数组 [英] PHP explode and put into array

问题描述

我有这样的线串

水果 - 香蕉|苹果|橙：食品薯条|香肠：甜品，冰淇淋|苹果派

在：（冒号）是主要议题分隔符，并在 | 为分隔符不同类型的子课题。

the : (colon) is the separator for the main topic, and the | is the separator for the different type of sub topics.

我试图引爆出来，放入数组，我需要的结果是这样的，以显示在下拉菜单中： -

I tried to explode it out and put it into array, I need the result to be something like this to be displayed in a drop down menu:-

    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！

推荐答案

您可以这样做：

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