[英]preg_match condition problem
I wan't to check if a string ($nick_2) got " or ñ 我不会检查字符串($ nick_2)是否为“或ñ
Is this correct? 这个对吗? i can't make it work 我不能使它工作
if ( (strlen($nick_2) >= 3) && (strlen($nick_2) <= 25) && (!preg_match("/\"/", $nick_2)) && (!preg_match("/ñ/", strtolower($nick_2))) ) {
For finding single characters, regexes are massive overkill. 对于查找单个字符,正则表达式会产生极大的过大杀伤力。 Just use 只需使用
if ((strpos('"', $nick_2) !== FALSE) || (strpos('ñ', $nick_2) !== FALSE)) {
... chars were found
}
Possibly your string is in UTF-8, in which case, you must use the u
modifier in preg_match
and should submit your expression to that function also in UTF-8. 可能您的字符串位于UTF-8中,在这种情况下,您必须在preg_match
使用u
修饰符,并且还应该在UTF-8中将表达式提交给该函数。
If that's the case, you will also want to do some of these things: 如果是这种情况,您还需要做以下一些事情:
