php - 解析由 html 表单发布的 php 中的数组

Question

我有以下问题。我的表单中有这些类型的选择:

<select name="variation[8][]" multiple>
   <option value="1">s</option>
   <option value="2">m</option>
   <option value="3">l</option>
</select>

<select name="variation[9][]" multiple>
   <option value="8">red</option>
   <option value="9">blue</option>
   <option value="10">black</option>
</select> 

我想用 php 正确读取发布的数组，我想在数据库中写入:

variation_id => 8 
variation_term => 1 
variation_id => 8 
variation_term => 2 
variation_id => 8 
variation_term => 3 

variation_id => 9 
variation_term => 8 
variation_id => 9 
variation_term => 9 
variation_id => 9 
variation_term => 10

我如何解析这个发布的数组？有更好的方法吗？

我找到了这个解决方案:

foreach ($_POST['variation'] as $key => $value) {
   for($i=0; $i<count($value); $i++){
     echo "varitaion name = $key"."<br>";
     echo "value = $value[$i]";
   }
}

尝试

foreach($_POST['variation'] as $key=>$val){
  if(is_array($val)){
     echo " Values for $key Are:"; // get your variation index eg:8,9 etc
     foreach($val as $key1=>$val1){
         echo $val1.","; // get the index values
     }
         echo "<br/>";
  }
}
