Array
(
    [sEcho] => 1
    [iTotalRecords] => 7521
    [iTotalDisplayRecords] => 1
    [aaData] => Array
        (
            [0] => Array
                (
                    [0] => Nordic Capital Buys SiC Processing
                    [1] => 2010-06-21/nordic-capital-buys-sic-processing
                    [2] => PEHub Media
                    [3] => Business
                    [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.

                    [6] => Admin, China, Frog Capital, Germany, Italy, Iyad Omari, Manufacturing, Norway, PEHub Media, Photovoltaic Wafer Manufacturing, Renewable Energy, Semiconductor, United States
                )

        )

)

echo json_encode($myArr);

{ “sEcho”： “1”， “iTotalRecords”：7521， “iTotalDisplayRecords”： “1”， “aaData”：[[” Nordic Capital购买SiC加工＆lt; / a＆gt;＆lt; / div＆gt;“，” 2010-06-21 / nordic-capital-buys-sic-processing＆lt; / div＆gt;“，”PEHub Media“，”Business“，”completed“， null ， “ Admin，China，Frog Capital，德国，意大利，Iyad Omari，制造业，挪威，PEHub媒体，光伏晶圆制造，可再生能源，半导体，美国]]}

请注意完成后字符串中间的空值

为什么这样，我需要执行什么转义/操作来编码呢？

我试过了，addslashes

Answer 1

从手册：

请注意，如果您尝试编码包含非utf值的数组，你将获得空值生成JSON字符串。您可以批量编码的所有元素 array_map函数的数组：

$encodedArray = array_map(utf8_encode, $myArr);
echo json_encode($encodedArray);

Answer 2

我刚刚尝试了完全相同的代码，并返回以下内容：

{"var1":"test string","var2":"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\u2019s founding family retains a 25% holding, while former lead investor Zouk Ventures retains a 5% stake.","var3":"test string 3"}

您运行的是哪个版本的PHP？这是来自您的本地主机还是您在远程盒子上运行它？

Answer 3

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（）。

Answer 4

在5.2.13上为我工作。确保您至少使用PHP 5.2.0并且PHP未使用--disable-json编译。您可能还想检查是否已启用错误报告（和/或日志记录）。

Answer 5

更简单的方法是$store_name = utf8_encode(name_of_varaible)，但请确保您的字符集为ISO-8859-1.

php json_encode返回null
