You can use html_entity_decode:
您可以使用html_entity_decode：
echo html_entity_decode('...', ENT_QUOTES, 'UTF-8');
Few notes:
几点注意事项：
Please note that it looks like you actually want to convert from HTML-encoded string(with entities like
) to ASCII AKA plaintext.This example converts to UTF-8which is ASCII-compatible character encoding for all ASCII characters (i.e. with char codes below 128). If you really want plain ASCII (thus loosing all accented characters and characters from foreign languages) you should strip all offending characters separately.
Last argument ('UTF-8') is necessary to keep compatibility with different PHP versions since the default value has changed since PHP 5.4.0.
请注意，看起来您实际上想要从 HTML 编码的字符串（带有像 的实体
）转换为 ASCII AKA 纯文本。此示例转换为UTF-8，这是所有 ASCII 字符（即字符代码低于 128）的 ASCII 兼容字符编码。如果您真的想要纯 ASCII（从而删除所有重音字符和外语字符），您应该单独删除所有有问题的字符。
最后一个参数 ('UTF-8') 是保持与不同 PHP 版本兼容所必需的，因为自 PHP 5.4.0 以来默认值已更改。
Update: Example with your text in ideone.
更新：以 ideone 中的文本为例。
Update2: Changed ENT_COMPAT to ENT_QUOTES by @Daan's suggestion.
更新 2：根据@Daan 的建议将 ENT_COMPAT 更改为 ENT_QUOTES。
