If you use htmlentities()to encode, you can use html_entity_decode()to reverse the process:
如果你使用htmlentities()编码，你可以使用html_entity_decode()逆向过程：
html_entity_decode()
html_entity_decode()
Convert all HTML entities to their applicable characters.
html_entity_decode()is the opposite of htmlentities()in that it converts all HTML entities in the string to their applicable characters.
将所有 HTML 实体转换为其适用的字符。
html_entity_decode()与htmlentities()相反，它将字符串中的所有 HTML 实体转换为其适用的字符。
e.g.
例如
$myCaption = 'áéí';
//encode
$myCaptionEncoded = htmlentities($myCaption, ENT_QUOTES);
//reverse (decode)
$myCaptionDecoded = html_entity_decode($myCaptionEncoded);

You want to look at html_entity_decodeand worry about which charset you should be using (probably ISO8859-1).
您想查看html_entity_decode并担心您应该使用哪个字符集（可能是 ISO8859-1）。
It may also be worth reading this articleabout character sets etc.
