preg_replace轮换PHP代码
preg_replace替换PHP代码
有一段PHP代码,我想让至之间的字符全部变为大写
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->a = '<a><?php $str = \'0\';if($str==\'0\'){echo $str;}?></a>';echo preg_replace("/<a>(.*?)/es",'"</a><a>".strtoupper("\\1")."</a>"',$a);
输出的结果总是不正确,总是把一些字符串当成PHP代码执行(例如输出的结果 $str 丢失),请问如何才能输出正确的结果?或者有没有其它的方法能实现?
谢谢了!
