$array1=["one"=>1];$array2=["two"=>2];$array1=["one"=>"one"];$array2=["two"=>"two"];$array=["one"=>0,"two"=>10,...$array1,...$array2];var_dump($array); 用…运算符解包$array1和array2,前一个数组的键被后一个数组的键所覆盖。输出结果如下
array array_diff_assoc(array $array1, array $array2[, array $...]) array_diff_assoc()返回一个数组,该数组包含了所有在array1中但是不在任何其它参数数组中的值。 注意和array_diff()不同的是键名也用于比较。 参数: array1 从这个数组进行比较 array2 被比较的数组 ... 更多比较的数组 返回值 返...
ThinkPHP5 提示 variable type error:array 是因为在 ThinkPHP5 中不允许在直接访问控制器时通过 return 方法直接返回数组。 出现这个错误时,使用 json 函数处理以下返回的数据即可,如: $data = [...]; return json($data); (adsbygoogle = window.adsbygoogle || []).push({});...
