用樹枝環行

Question

如何用樹枝做到這一點？

foreach($estimate_data AS $year => $month) { 
     foreach ($month AS $monthNo => $estimates) { 
      $chart_data .= "['". $year ."/".$monthNo."',"; 
      foreach (array(0, 1, 3, 5, 8, 13, 20) AS $est){ 
       $chart_data .= (isset($estimates[$est]) ? $estimates[$est] : 0) .","; 
      } 
      $chart_data .= "],\n"; 
     } 
    } 

這是我到目前爲止，但我與內的foreach掙扎和檢查元素的存在數組中：

 {% for year, month in chart_data %} 
     {% for month_no, estimates in month %} 
      ['{{year}}/{{month_no}}', 
      {% for i in [0, 1, 2, 3, 5, 8, 13, 20] %} 
      {% if estimates %} 
      {{estimates[i]}} , 
      {% endif %} 
      {% endfor %} 
     {% endfor %} 
     {% endfor %}

試試這個..

未經測試!!

{% for year, month in estimate_data %} 
    {% for month_no, estimates in month %} 
     {% set chart_data = chart_data ~ "['" ~ year ~ "/" ~ monthNo ~ "'," %} # concat the strings 
     {% for est in [0, 1, 3, 5, 8, 13, 20] %} 
      {% set chart_data = chart_data ~ (defined estimates.est) ? estimates.est : 0 ~ ',' %} # if estimates.est is defined 
     {% endfor %} 
     {% set chart_data = chart_data ~ "],\n" %} # concat the final string. 
    {% endfor %} 
{% endfor %} 

編輯： 我想，如果你嘗試使用到Concat的：

{% set variable ~= 'text' %} 

這應該工作，但是我甚至不考這個..
