Ive encountered a weird problem when outputting an array using json_encode($string).
This problem arises if I call $name = mb_substr($name, 0, 100); and the last character (at $name[100]) happens to be a special character on a string that is written to the database and then outputted with json_encode() later.
I am encoding the string before hand with $string1 = mysql_real_escape_string ( $string ); and then $string1 = mb_convert_encoding($string1, "UTF-8", "auto"); to make sure the strings are UTF-8 (the DB charset is UTF-8 too). If I do this, I can store the new string in the database, SELECT it into an array, but json_encode() fails.
If I do not split the string to start with, everything works fine.
I have already tried encoding with $response = array_map('utf8_encode', $response);, json_encode ( $response, true ) and json_encode ( $response, JSON_UNESCAPED_UNICODE ). However none of the above has worked.
So in essence my question is: How do get the substring of a string (from position 0 - 100) and ignoring a special character that may be split in half at the end of the string?
An example string that I have split that cannot be JSON encoded
