php - Json Decode giving empty result if there is any special character is there -

while using json_decode, if there exist special charecter "question mark black diamond" decode returns empty values.

i have used utf-8 encode also.

your problem seems in json_encode part , not in json_decode part.

take @ this: how keep json_encode() dropping strings invalid characters

they suggest use iconv before json_encode string sure remove illegal characters.

to quote example given:

$stripped_of_invalid_utf8_chars_string = iconv('utf-8', 'utf-8//ignore', $orig_string); if ($stripped_of_invalid_utf8_chars_string !== $orig_string) {     // 1 or more chars invalid, , stripped out.     // if need know in string first stripped character was,      // see https://stackoverflow.com/questions/7475437/find-first-character-that-is-different-between-two-strings } $json = json_encode($stripped_of_invalid_utf8_chars_string);
