thinkphp keyword highlighting

First define a function in function.php:

//关键字描红
function keywords_red($string,$keywords=''){
    if(empty($keywords)||empty($string)) return $string;
    return str_replace($keywords,'<span class="red">'.$keywords.'</span>',$string);
}

Then write this in the template variable

{$<pre name="code" class="php">/*
**参数说明
**$sheng为页面输出的变量
**$keywords_red即是描红函数
**###代表第一个参数，即$sheng
**$q代表需要描红的字体，即搜索的关键字
*/

sheng|keywords_red=###,$q}

The above introduces thinkphp keyword tracing, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
