utf8_encode

(PHP 4, PHP 5, PHP 7)

utf8_encodeEncodes an ISO-8859-1 string to UTF-8

Description

utf8_encode ( string $data ) : string

This function converts the string data from the ISO-8859-1 encoding to UTF-8.

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.

Parameters

data

An ISO-8859-1 string.

Return Values

Returns the UTF-8 translation of data.

Changelog
