Well I found the solution. 好吧,我找到了解决方案。
Havelock suggested to print json_last_error_msg()
and I found malformed UTF-8 characters, possibly incorrectly encoded. Havelock建议打印json_last_error_msg()
,我发现格式错误的UTF-8字符,可能编码错误。
I am using MySQLi
so I have to put this line in after database connection for character formatting: mysqli_set_charset($conn, "utf8");
我正在使用MySQLi
因此必须在数据库连接后将此行放入字符格式设置中: mysqli_set_charset($conn, "utf8");
. 。
Thanks Havelock. 谢谢哈夫洛克。
