If you utf8_encode() on a string that is already UTF-8 then it looks garbled when it is encoded multiple times. I made a function toUTF8() that converts strings into UTF-8. You don't need to specify what the encoding of your strings is.
You should set your default_charset to UTF-8: default_charset = "utf-8". (PHP Cookbook may have a typo in it if they ask you to change the default_encoding — I've never heard of it.) You'll also want to make sure that your web server is set to output UTF-8 if you're going to outputting UTF-8 encoded characters.
Detects the most likely character encoding for string string from an ordered list of candidates. Automatic detection of the intended character encoding can never be entirely reliable; without some additional information, it is similar to decoding an encrypted string without the key.
PHP UTF-8 Encoding – modifications to your code: To be sure that your PHP code plays well in the UTF-8 data encoding sandbox, here are the things you need to do: Set UTF-8 as the character set for all headers output by your PHP code. In every PHP output header, specify UTF-8 as the encoding: header('Content-Type: text/html; charset=utf-8');
17 maj 2021 · Common encoding-related errors in PHP Malformed UTF-8 characters, possibly incorrectly encoded. When transforming an array to JSON with json_encode, you might run into this issue. This just means that what PHP was expecting to get as UTF-8 is not in that encoding, so we can solve the problem by converting it first:
mb_convert_encoding (array | string $string, string $to_encoding, array | string | null $from_encoding = null): array | string | false. Converts string from from_encoding, or the current internal encoding, to to_encoding. If string is an array, all its string values will be converted recursively.
The utf8_encode () function encodes an ISO-8859-1 string to UTF-8. Unicode is a universal standard, and has been developed to describe all possible characters of all languages plus a lot of symbols with one unique number for each character/symbol.
