utf8_encode — 将字符串从 ISO-8859-1 转换为 UTF-8 编码
此函数自 PHP 8.2.0 起弃用。强烈建议不要应用此函数。
$string): string
该函数将 string 字符串从 ISO-8859-1
编码转换为 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-8859-1character 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.

| 版本 | 说明 |
|---|---|
| 8.2.0 | 弃用此函数。 |
| 7.2.0 | This function has been moved from the XML extension to the core of PHP. In previous versions, it was only available if the XML extension was installed. |
示例 #1 基础示例
<?php
// Convert the string 'Zoë' from ISO 8859-1 to UTF-8
$iso8859_1_string = "\x5A\x6F\xEB";
$utf8_string = utf8_encode($iso8859_1_string);
echo bin2hex($utf8_string), "\n";
?>
以上例程会输出：
