php json encode 中文部分被替换为 unicode 码 ,应该怎么用最简单的方法解决?

[GPU]

	if(!$_GET['username']||!$_GET['password']||!$_GET['domain']){
	exit(urldecode(json_encode(array('msg'=>'username,password,domain 参数必选'))));
	}

代码如上 ,

此代码json输出网页的东西是这样子的
" {"msg":"username,password,domain \u53c2\u6570\u5fc5\u9009"}"


完整版如下,

	<?php
	error_reporting(0);
	set_time_limit(0);
	header('Content-type:text/html; charset=utf-8');
	if(!$_GET['username']||!$_GET['password']||!$_GET['domain']){
	exit(json_encode(array('msg'=>'username,password,domain 参数必选')));
	}
	$domain = explode("@", $_GET['domain']);
	$config = array(
	'login_email' => $_GET['username'],
	'login_password' => $_GET['password'],
	'sub_domain' => $domain[0],
	'domain' => $domain[1],
	'record_line' => $_GET['line']?$_GET['line']:'默认',

5.4 之后 echo json_encode("中文", JSON_UNESCAPED_UNICODE);

5.4 之前 echo json_encode(urlencode("中文"));接收端 json_decode 后再 urldecode

[GPU]

@anewg 5.4 是什么意思？

[anewg]

@GPU php版本5.4

[GPU]

@anewg
https://gist.github.com/anonymous/6d8f133df10314942724

改了一下, 成这样子 ,输出正常 .不知道有没有可以写得更简化的呢?

[iyaozhen]

其实没关系的，接收的时候php_decode会把编码还原。
js我用jquery接收，不用任何处理data.msg直接获取就行。
一楼说的php5.4之后的JSON_UNESCAPED_UNICODE参数可以直接输出中文。

[zakokun]

先把中文urlencode一下，处理完以后再转回来urldecode

[anewg]

@GPU 你用5.4以上的php的话这样是最简了

[GPU]

@anewg 嗯. 好的.

[bombless]

我还以为是指读不出来unicode编码呢…
这种编码算是一种惯例了，不明白为啥要改

[tmkook]

function jsonEncode($arr){
$json = json_encode($arr);
return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", $json);
}

放出我的必杀技！！！

[GPU]

@tmkook 看不懂啊

[tmkook]

@GPU echo jsonEncode(array("test":"中文")); 生成：{"test":"中文"}

[GPU]

@tmkook 这个技能貌似真的很屌

[Actrace]

一个比较容易懂的做法是先把数组内的元素都用urlencode处理成不需要转换的字符串,然后生成JSON字符串后再用urldecode来对整个JSON字符串进行解码(中文等将被还原),类似于金属提纯.
不过看了10楼的做法,感觉10楼效率上会有很大的优势,毕竟是正则替换,而且相对于上面提出的方案少了一个转换的流程.
