求php如何输出josn带数组

[兽兽]

$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);

这样只是两个大括号
我想要这样的

{"errno":0,"errmsg":"ok","ret":[{"provice":"贵州"},{"provice":"江西"},{"provice":"湖北"},{"provice":"云南"},{"provice":"浙江"},{"provice":"辽宁"},{"provice":"河北"},{"provice":"宁夏"},{"provice":"江苏"},{"provice":"广东"},{"provice":"四川"},{"provice":"海南"},{"provice":"山东"},{"provice":"安徽"},{"provice":"湖南"},{"provice":"新疆"},{"provice":"河南"},{"provice":"福建"}]}

把你期望的 json 解码不就知道了

$s = '{"errno":0,"errmsg":"ok","ret":[{"provice":"贵州"},{"provice":"江西"},{"provice":"湖北"},{"provice":"云南"},{"provice":"浙江"},{"provice":"辽宁"},{"provice":"河北"},{"provice":"宁夏"},{"provice":"江苏"},{"provice":"广东"},{"provice":"四川"},{"provice":"海南"},{"provice":"山东"},{"provice":"安徽"},{"provice":"湖南"},{"provice":"新疆"},{"provice":"河南"},{"provice":"福建"}]}';
print_r(json_decode($s, 1));

Array
(
    [errno] => 0
    [errmsg] => ok
    [ret] => Array
        (
            [0] => Array
                (
                    [provice] => 贵州
                )

            [1] => Array

            [3] => Array

                    [provice] => 湖南
                )

            [15] => Array

                )

[一起混吧]

用json_decode 反向过来就是你要构造的数组结构

[兽兽]

呃！麻烦大大帮看看，
Parse error: syntax error, unexpected '[', expecting ')' in C:\wwwroot\8888.php on line 11

[兽兽]

$arr = Array(
    'errno' => 0,
    'errmsg' => ok,
    'ret' => Array
      [('[17]' => Array
                (
                    '[provice]' => 福建
                )
 
        )]
 
);
echo json_encode($arr);

怎么才能输出中括号呢，大大
