今天遇到一个很奇怪的问题，在使用json_decode的时候，遇到一个奇怪的问题，在遇到中文字符组的时候，怎么都解析不了，把这个中文的字段删除，里面就能解析了....搞了半天不知道哪里的问题，路过的大虾帮忙看看

	$nodeAry=array();	while($row=mssql_fetch_array($rs)){		$description=strstr("//","",$row['description']);	   array_push($nodeAry,'{"fchrItemID":"'.$row["fchrItemID"].'","fchrItemTypeID":"'.$row["fchrItemTypeID"].'","fchrItemName":"'.$row["fchrItemName"].'","flotQuotePrice":"'.$row["flotQuotePrice"].'","description":"'.trim($description).'","fdtmLastModifyTime":"'.$row["fdtmLastModifyTime"].'","sales_volume":"'.$row["sales_volume"].'"}');    }	$tbstr=implode(',',$nodeAry);   ?>{"table":[<?=$tbstr;?>]}

这里的description 字段有中文，只要把这个字段去掉就可以了，

 header("Content-Type:text/html; charset=utf-8");		$ch = curl_init();	curl_setopt($ch, CURLOPT_URL, $remoteAPIBasePath . "sync2shop_api/item.php");	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);	curl_setopt($ch, CURLOPT_HEADER, 0);	$output = curl_exec($ch);		curl_close($ch);		$obj=json_decode(iconv("gb2312","utf-8",$output));	var_dump( $obj);	//$obj=json_decode($output);	$rscount=count($obj->table);		$han=fopen("debug.php","a");	fwrite($han,$output."---------".$rscount);	fclose($han);

我是这么解析的，不知道哪里有错误，有谁帮忙看看！

回复讨论(解决方案)

php 的 json 函数只对 utf-8 编码的的字符串有效

你需要先将字符串转成 utf-8 编码的，然后再解码

只能说你拿到的 json 不合规范，中文应该都是 \uxxxx 形式

已经设置编码utf-8 编码了，但是还是不行啊

只能说你拿到的 json 不合规范，中文应该都是 \uxxxx 形式

数据取出的数据怎么会有反斜杠呢？自己加一个么？

我的数据是从远程数据库取的，难道会有影响吗？

你最好贴出你的数据，只要格式正确。不会有问题的

$s = '{"a":"我的","b":"数据","c":["是从远程数据库","取的"],"d":"难道会有影响吗？"}';$s = iconv('gbk', 'utf-8', $s);print_r(json_decode($s));

stdClass Object(    [a] => 我的    [b] => 数据    [c] => Array        (            [0] => 是从远程数据库            [1] => 取的        )    [d] => 难道会有影响吗？)

我只截取一部分，数据太多了，麻烦帮忙看看呐！

能帮我远程弄一下么？我用了curl_init(),curl_exec() ,输出流，获取的

$ch = curl_init();	curl_setopt($ch, CURLOPT_URL, $remoteAPIBasePath . "sync2shop_api/item.php");	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);	curl_setopt($ch, CURLOPT_HEADER, 0);	$output = curl_exec($ch);		curl_close($ch);			$obj=json_decode(iconv("gb2312","utf-8",$output));

这里的$output 打印出来就是json的东西，不是直接写在里面的

如果向你这么写，为啥我的会报错呢？

 header("Content-Type:text/html; charset=utf-8");		$ch = curl_init();	curl_setopt($ch, CURLOPT_URL, $remoteAPIBasePath . "sync2shop_api/item.php");	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);	curl_setopt($ch, CURLOPT_HEADER, 0);	$output = curl_exec($ch);	curl_close($ch);		$obj=<<< TXT var_dump($output) TXT;	$obj=json_decode(iconv("gb2312","utf-8",$output));		echo count($obj->table);

程序文件保存为UTF-8编码。
item.php那个文件的字符集是什么？是否有转码的必要？
一般从GBK转UTF-8比较好。

如果想用json_decode解析gbk编码。很容易。只要转换为utf8编码既可。
具体实现和原因可以查看这篇日志
http://www.bo56.com/%E5%9C%A8php%E4%B8%AD%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8json_decode%E8%A7%A3%E6%9E%90gbk%E7%BC%96%E7%A0%81%E7%9A%84json%E5%AD%97%E7%AC%A6%E4%B8%B2/

在php中如何使用json_decode解析gbk编码的json字符串

程序文件保存为UTF-8编码。
item.php那个文件的字符集是什么？是否有转码的必要？
一般从GBK转UTF-8比较好。

item 文件是utf-8 的

$output 是你用 curl 从 item.php 获取的
而 item.php 是 utf-8 的
那么
首先检查 item.php 及其相关的文件是否有 BOM 头
其次检查数据库读出的内容是否为 utf-8 的

$output 是你用 curl 从 item.php 获取的
而 item.php 是 utf-8 的
那么
首先检查 item.php 及其相关的文件是否有 BOM 头
其次检查数据库读出的内容是否为 utf-8 的

从output 看 utf-8 的，item 文件没有bom ，
但是用json_decode($output ) ,发现count 是0 ，应该还是解析json 的问题

$obj=json_decode(iconv("gb2312","utf-8",$output));
var_dump( $obj);
输出$obj看下，看是否是一个完整的json格式。

$output = curl_exec($ch);
取到 $output 后
echo base64_encode(substr($output, 0, 200));
贴出结果

无语了

http://218.85.194.210:8888/sync2shop_api/item.php ,这里是远程的json 数据

你在改数据？

你在改数据？

我在同步远程的数据，往本地数据库插入啊，远程的json 传过来，解析不了，本地也就没东西了

现在从 http://218.85.194.210:8888/sync2shop_api/item.php 得到的数据中已经已经没有中文了

item.php是远程的，utf-8，那么你获取的item.php里的数据也是UTF-8的，应该没有转码的必要了。

先urlencode在json然后urldecode

问题已经解决，谢谢各位的帮助！

我是用了加密解密函数，实现的json 传送的...
