(PHP 4, PHP 5, PHP 7)
utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1
$data
)
This function converts the string data from the
UTF-8 encoding to ISO-8859-1. Bytes
in the string which are not valid UTF-8, and
UTF-8 characters which do not exist in
ISO-8859-1 (that is, characters above
U+00FF) are replaced with ?.
Note:
Many web pages marked as using the ISO-8859-1 character encoding actually use the similar Windows-1252 encoding, and web browsers will interpret ISO-8859-1 web pages as Windows-1252. Windows-1252 features additional printable characters, such as the Euro sign (€) and curly quotes (“ ”), instead of certain ISO-8859-1 control characters. This function will not convert such Windows-1252 characters correctly. Use a different function if Windows-1252 conversion is required.
dataA UTF-8 encoded string.
Returns the ISO-8859-1 translation of data.
