如何反转htmlentities()? [英] How to reverse htmlentities()?

问题描述

对于特殊字符，例如áéí，我可以拨打htmlentities():

For special characters like áéí, I can call htmlentities():

$mycaption = htmlentities($mycaption, ENT_QUOTES);

要获取相应的html实体:

To get the corresponding html entities:

áéí

如何将其恢复为áéí?

推荐答案

如果使用htmlentities()进行编码，则可以使用html_entity_decode()来逆转该过程:

If you use htmlentities() to encode, you can use html_entity_decode() to reverse the process:

将所有HTML实体转换为适用的字符.

Convert all HTML entities to their applicable characters.

html_entity_decode()与 htmlentities( )，因为它将字符串中的所有HTML实体转换为它们的适用字符.

html_entity_decode() is the opposite of htmlentities() in that it converts all HTML entities in the string to their applicable characters.

例如

$myCaption = 'áéí';

//encode
$myCaptionEncoded = htmlentities($myCaption, ENT_QUOTES);

//reverse (decode)
$myCaptionDecoded = html_entity_decode($myCaptionEncoded);
