请告诉我可以用来从字符串中删除这些特殊代码字符的任何函数.

Please tell me any function which I can use to remove these special code chars from my string.

推荐答案

或者使用html_entity_decode对其进行解码，或者使用preg_replace将其删除:

Either decode them using html_entity_decode or remove them using preg_replace:

$Content = preg_replace("/&#?[a-z0-9]+;/i","",$Content); 

(摘自此处)

根据雅科的评论选择

最好用'+'代替 {2,8}之类的.这将限制 更换整个的机会 未编码的'&'句子是 礼物.

might be nice to replace the '+' with {2,8} or something. This will limit the chance of replacing entire sentences when an unencoded '&' is present.

$Content = preg_replace("/&#?[a-z0-9]{2,8};/i","",$Content);
