在Twig模板中显示数组

Have problem to display an array in a Twig template.

In mysql I have a text field with value: testtest-testtest2-testtest3

In the controller I explode by '-' and pass it to Twig like so: 

$ingred[] = explode('-', $ingreds);
$this->twig->render(['ingred' => $ingred]);

In the Twig template I loop through and it works:

   {% for ing in ingred %}
     <span class="ingridiantai">{{ ing.0 }}</span>
     <span class="ingridiantai">{{ ing.1 }}</span>
     <span class="ingridiantai">{{ ing.2 }}</span>
     <span class="ingridiantai">{{ ing.3 }}</span>
     <span class="ingridiantai">{{ ing.4 }}</span>
     <span class="ingridiantai">{{ ing.5 }}</span> 
   {% endfor %}

But what I want is to loop through all values without writing their key. Like this:

   {% for ing in ingred %}
     <span class="ingridiantai">{{ ing }}</span> 
   {% endfor %}

How can I do what? I was searching in the docs, but didn't find anything that would work for me.

在Twig模板中显示数组时出现问题。

在mysql中 我有一个值为的文本字段： testtest-testtest2-testtest3

在控制器中我按' - '爆炸并将其传递给Twig，如下所示： 

  $ ingred [] = explode（' - '，$ ingreds）; 
 $ this-＆gt; twig-＆gt; render（['ingred'=＆gt; $  ingred]）; 
   
 
 
在Twig模板中，我循环完成它的工作原理： 
 
 
  {％for ing  in ingred％} 
＆lt; span class =“ingridiantai”＆gt; {{ing.0}}＆lt; / span＆gt; 
＆lt; span class =“ingridiantai”＆gt; {{ing.1}}＆lt; /  span＆gt; 
＆lt; span class =“ingridiantai”＆gt; {{ing.2}}＆lt; / span＆gt; 
＆lt; span class =“ingridiantai”＆gt; {{ing.3}}＆lt; / span＆gt;  
＆lt; span class =“ingridiantai”＆gt; {{ing.4}}＆lt; / span＆gt; 
＆lt; span class =“ingridiantai”＆gt; {{ing.5}}＆lt; / span＆gt;  
 {％endfor％} 
   
 
 
但我想要的是在不写入密钥的情况下遍历所有值。 像这样： 
 
 
  {％for ing in ingred％} 
＆lt; span class =“ingridiantai”＆gt; {{ing}}＆lt; / span＆gt;  
 {％endfor％} 
   
 
 
我该怎么办？ 我在文档中搜索，但没有发现任何对我有用的东西。

    Using [] adds an element to an array and explode also creates an array. So now you have a 2-dimensional array.

    Simply change the code in your controller to

    $ingred = explode('-', $ingreds);
