在URL至少包含1个大写字母的情况下，我正在尝试在php中进行html重定向.
I'm trying to do html redirects in php in cases where the url contains at least 1 upper case letter.
示例: http://www.domain.com/Michael_Jordan 需要重定向到 http://www.domain.com/michael_jordan -唯一的问题是我似乎找不到脚本来检测是否存在至少1个大写字母.
example: http://www.domain.com/Michael_Jordan needs to be redirected to http://www.domain.com/michael_jordan - only problem is I can't seem to find a script to detect if at least 1 capital letter exists.
推荐答案
Some regular expression should be able to the work, you can use preg_match and [A-Z]
if(preg_match('/[A-Z]/', $domain)){
// There is one upper
}
