utf8_encode — Converts a string from ISO-8859-1 to UTF-8
This function has been DEPRECATED as of PHP 8.2.0. Relying on this function is highly discouraged.
Description
$string): string
This function converts the string string from the
ISO-8859-1 encoding to UTF-8.
Note:
This function does not attempt to guess the current encoding of the provided string, it assumes it is encoded as ISO-8859-1 (also known as "Latin 1") and converts to UTF-8. Since every sequence of bytes is a valid ISO-8859-1 string, this never results in an error, but will not result in a useful string if a different encoding was intended.
Many web pages marked as using the
ISO-8859-1character encoding actually use the similarWindows-1252encoding, and web browsers will interpretISO-8859-1web pages asWindows-1252.Windows-1252features additional printable characters, such as the Euro sign (€) and curly quotes (“”), instead of certainISO-8859-1control characters. This function will not convert suchWindows-1252characters correctly. Use a different function ifWindows-1252conversion is required.
Parameters
-
string -
An ISO-8859-1 string.
Return Values
Returns the UTF-8 translation of string.
