utf8_encode — Converts a string from ISO-8859-1 to UTF-8
$string
): string
This function converts the string string
from the
ISO-8859-1
encoding to UTF-8
.
注意:
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-8859-1
character encoding actually use the similarWindows-1252
encoding, and web browsers will interpretISO-8859-1
web pages asWindows-1252
.Windows-1252
features additional printable characters, such as the Euro sign (€
) and curly quotes (“
”
), instead of certainISO-8859-1
control characters. This function will not convert suchWindows-1252
characters correctly. Use a different function ifWindows-1252
conversion is required.
