echo json_encode($myArr);

{"sEcho":"1","iTotalRecords":7521,"iTotalDisplayRecords":"1","aaData":[[" Nordic Capital Buys SiC Processing</a></div>"," 2010-06-21/nordic-capital-buys-sic-processing</div>","PEHub Media","Business","completed",null," Admin, China, Frog Capital, Germany, Italy, Iyad Omari, Manufacturing, Norway, PEHub Media, Photovoltaic Wafer Manufacturing, Renewable Energy, Semiconductor, United States]]}

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

  • Works for me. Check your PHP configuration, I think json_* stuff can be disabled. Commented Jul 5, 2010 at 15:38
  • Please provide the PHP code used to construct the example array (and please check your questions carefully when posting - examples provided should do what you intend them to!) Commented Jul 5, 2010 at 16:06

From the manual:

Note that if you try to encode an array containing non-utf values, you'll get null values in the resulting JSON string. You can batch-encode all the elements of an array with the array_map function:

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

Thanks seengee, perfect. I actually used array_map(htmlentities... for my situation, but this saved the day.
It should be noted that suggesting utf8_encode() is not usually a great idea, as it blindly assumes the input is ISO-8859-1. If you're facing the problem, it's important that you first figure out what your character set IS, and only THEN convert (php.net/iconv can help with the second part if you're NOT dealing with ISO-8859-1).

Actually it doesn't return null, http://codepad.org/A34KdUf5.

Maybe your PHP version doesn't support json_encode().

Please check my question again i have updated with full code, as json_encode is working with rest of array.
In copying and pasting, you probably inadvertently put it in UTF-8 form, while the original string likely wasn't.

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.

The simpler way is $store_name = utf8_encode(name_of_varaible) but please make sure that your character set is ISO-8859-1.
