dlang语言实现php的array_diff函数最好支持关联数组功能描述如下：array_diffarray $array array $arrays arrayCompares array against one or more other arrays and returns the values in array that are not present in any of the oth

以下是dlang语言实现支持关联数组的array_diff函数的完整代码：

/**

• 比较多个数组的差异

• array_diff(["a"=>1,"b"=>2,"c"=>3], ["a"=>1,"b"=>4,"d"=>5], ["a"=>2,"b"=>2,"e"=>6])

• ==> ["c"=>3] */ V[string] array_diff(V)(V[string] a, V[string][] b...) { V[string] result;

  // 遍历a数组 foreach (key, value; a) { bool found = false;

   // 遍历b数组
   foreach (arr; b) {
       if (arr.canFind(key) && arr[key] == value) {
           found = true;
           break;
       }
   }
  
   // 如果a中的元素在b数组中没有找到，则添加到结果数组中
   if (!found) {
       result[key] = value;
   }
  

  }

  return result; }

/**

• 比较两个数组的差异
• array_diff(["a"=>1,"b"=>2,"c"=>3], ["a"=>1,"b"=>4,"d"=>5]) ==> ["b"=>2,"c"=>3] */ V[string] array_diff(V)(V[string] a, V[string] b) { return array_diff(a, [b]);
