用于将html实体转换为html特殊字符的PHP函数

Question

I have this function for converts html entities back to html special characters:

function html_entity_decode_utf8($value, $double_encode = TRUE) 

{
    return htmlspecialchars( (string) $value, ENT_QUOTES, "UTF-8", $double_encode);


}

Now, I need to Print this:

echo html_entity_decode_utf8('&zwnj');

Output is:

&zwnj

Why htmlspecialchars notwork ?! how i can fix this?

Answer 1

htmlspecialchars converts & into & . To convert back, you need htmlspecialchars_decode :

function html_entity_decode_utf8($value) 
{
    return htmlspecialchars_decode( (string) $value, ENT_QUOTES);
}

To see more options for using this function, check out the documentation .
