Php json_使用大字符串编码

我在json对象字段

$o->sHtml

中返回一个html响应

测试

sHtml

大约有13000个字符，在

json\u encode

its

$o->sHtml=null

之后。

知道为什么吗？

Json编码只适用于UTF-8编码的数据。检查您的输入数据是否为utf8

$json  = json_encode($o->sHtml); //or json_encode($o);
$error = json_last_error();
var_dump($json, $error === JSON_ERROR_UTF8);

这些都是可能的错误

JSON_ERROR_NONE -   No error has occurred    
JSON_ERROR_DEPTH -  The maximum stack depth has been exceeded    
JSON_ERROR_STATE_MISMATCH - Invalid or malformed JSON    
JSON_ERROR_CTRL_CHAR -Control character error, possibly incorrectly encoded  
JSON_ERROR_SYNTAX - Syntax error     
JSON_ERROR_UTF8 -   Malformed UTF-8 characters, possibly incorrectly encoded
