php正则匹配sgncwap_PHP正则表达式匹配关键字之外HTML标签a

我能够做到我想要的东西(不使用正则表达式)由&＃xff1a;

解析我的字符串

删除所有标签(将它们复制到一个临时数组&＃xff0c;并保持一个占位符的每个字符在字符串上)

str_replace新字符串为了替换所有关键字

重新填充它原来的占位符个标签

这是我使用的代码&＃xff0c;如果别人需要它&＃xff1a;

$str &＃61; <<

Moses supposes his toeses are roses,

but Moses supposes erroneously;

for nobody&＃39;s toeses are posies of roses,

as Moses supposes his toeses to be.

Ganda Moses!
