php json_encode 返回 null
Array

[0] => Nordic Capital Buys SiC Processing

[4] => completed
[5] => Nordic Capital has acquired a 70% stake in SiC Processing AG, a German industrial recycling company, from Frog Capital. No sale price was disclosed. SiC Processing’s founding family retains a 25% holding, while former lead investor Zouk Ventures retains a 5% stake.

)
echo json_encode($myArr);
{"sEcho":"1","iTotalRecords":7521,"iTotalDisplayRecords":"1","aaData":[[" Nordic Capital 收购 SiC 加工业务"," 2010-06-21/nordic-capital-buys-sic-processing","PEHub Media","业务","已完成",null, ” 管理员，中国，Frog Capital，德国，意大利，Iyad Omari，制造业，挪威，PEHub Media，光伏晶圆制造，可再生能源，半导体，美国]]}
完成后注意字符串中间的空< /strong>
为什么会这样，我需要执行什么转义/操作才能对其进行编码？
我已经尝试过，addslashes

Note the null in the middle of the string after completed
Why is this, what escape/manipulation do I need to perform in order to encode this?
I have tried, addslashes

从手册：
From the manual:
实际上它不会返回 null，http://codepad.org/A34KdUf5。
也许您的 PHP 版本不支持 json_encode()。
Actually it doesn't return null, http://codepad.org/A34KdUf5.
Maybe your PHP version doesn't support json_encode().
在 5.2.13 上为我工作。确保您至少使用 PHP 5.2.0 并且 PHP 不是使用 --disable-json 编译的。您可能还想检查是否启用了错误报告（和/或日志记录）。
Works for me on 5.2.13. Ensure you're using at least PHP 5.2.0 and that PHP wasn't compiled with --disable-json. You may also want to check that error reporting (and/or logging) is enabled.
更简单的方法是
$store_name = utf8_encode(name_of_varaible)但请确保您的字符集是ISO-8859-1。The simpler way is
$store_name = utf8_encode(name_of_varaible)but please make sure that your character set isISO-8859-1.
