一种编码风格,MyScoreIphone
转换成另一种编码风格 my_score_iphone
应该怎样做,分别使用java和php实现
其中,php使用函数
请多指教!
回复讨论(解决方案)
<?php$funcname = 'MyScoreIphone';$newfuncname = change($funcname);echo $funcname.'<br>';echo $newfuncname;function change($str){ $newstr = preg_replace_callback('/[A-Z]{1}/', 'f', $str); return substr($newstr, 1);}function f($str){ return '_'.strtolower($str[0]);}?>
我想到了使用正则preg_replace,
可是不知道第二个参数怎样使,
原来还有preg_replace_callback,

Second, reasoning skills are limited and cannot make logical inferences or fuse facts from multiple data sources. When faced with more complex and open-ended questions, LLM's answers may become absurd or contradictory, known as "illusions." Therefore, although LLM is very useful in some aspects, it still has certain limitations when dealing with complex problems and real-world situations.
