我有一张X超文本,请人们填写他们的全名。 然后,我与<代码>preg_match()一致使用这一模式:/^[p{L}s]+$/。
On my local server running PHP 5.2.13 (PCRE 7.9 2009-04-11) this works fine. On the webhost running PHP 5.2.10 (PCRE 7.3 2007-08-28) it doesn t match when the entered string contains the Danish Latin character ø ( http://www.ltg.ed.ac.uk/~richard/utf-8.cgi?input=%F8&mode=char ).
这难道是一种ug吗? 是否有工作?
事先感谢你!
So, the problem is as presumed. You are not using the /u modifier. This means that PCRE will not look for UTF-8 characters.
无论如何,应当如何做到:
var_dump(preg_match( /^[p{L}s]+$/u , "ø"));
我的所有版本都做了工作。 其他人可能会有ug,但这种情况不大可能。
您的问题是,这还有助于:
var_dump(preg_match( /^[p{L}s]+$/ , utf8_decode("ø")));
通知说,这使用ISO-8859-1而不是UTF-8,并删除了<代码>/u。 结果是int(1)。 英文字母缩略语 以非<代码>/u为格式。 (单一方位数×A0-xFF的多数是拉丁-1的字母符号,8位位代码与统法协会编码的相同,因此实际上ok。)
结论: 你的投入实际上是ISO-8859-1。 因此,它没有<代码>/u就意外地为你工作。 改变这种变化,并采用投入果园。
