  PHP 中 正则表达式转化小写下划线变量变驼峰式
   

$method = 'set'.preg_replace(
      "/(?:^|_)([a-z])/e", 
             "strtoupper('\\1')", 
             $f);
Copy after login

如

 first_name -> setFirstName
   click_url -> setClickUrl
Copy after login

正则中的/e可以执行. 此特性在perl中也是存在的.

如果不可以执行那只能

a -> A
 b -> B
 ...
 z -> Z
Copy after login

不知道还有没有别的办法.
