utf8_encode 将字符串从 ISO-8859-1 转换为 UTF-8 编码 &warn.deprecated.function-8-2-0; &reftitle.description; #[\Deprecated] stringutf8_encode stringstring 该函数将 string 字符串从 ISO-8859-1 编码转换为 UTF-8。 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 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. &reftitle.parameters; string ISO-8859-1 字符串。 &reftitle.returnvalues; 返回 string 的 UTF-8 翻译。 &reftitle.changelog; &Version; &Description; 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. &reftitle.examples; ]]> &example.outputs; &reftitle.notes; 从 PHP 8.2.0 开始，弃用此函数，并将在未来的版本中删除。应检查现有用途并用适当的替代方案。 类似的功能可以通过 mb_convert_encoding 实现，支持 ISO-8859-1 和许多其他字符编码。 ]]> &example.outputs; 根据安装的扩展，其他有效选项是 UConverter::transcode 和 iconv。 以下都给出相同的结果： ]]> &example.outputs; &reftitle.seealso; utf8_decode mb_convert_encoding UConverter::transcode iconv
