大致上的原理是你添加在文本上的不是html语言标记。而是你的ubb标记。然后通过正则去匹配他。输出的时候匹配回html标记

正则表达式！！

不用正则不行吗

可以，不过比较难实现！

function ubb($txt) { //UBB 处理函数
        $pattern = array(
        "/\[b\](.+?)\[\/b\]/is",
        "/\[i\](.+?)\[\/i\]/is",
        "/\[u\](.+?)\[\/u\]/is",
        "/\[font=([^\[]*)\](.+?)\[\/font\]/is",

        "/\[url\]www\.([^\[]*)\[\/url\]/is",

        $replacement = array(
