Could someone please help me to highlight the searchterm in my php search code? Below is the code that I am currently using, and it works fine. Would just like to add a highlight function but have no idea how to implement that on this code without redoing the whole thing.
我遇到了<span>效果，但无法将它放入<table>中以仅突出显示搜索词并仍然在表中循环.

$con = mysql_connect($host, $db_user, $db_pass);
if (!$con)

推荐答案
最简单的解决方案是使用 str_replace() 将搜索字词替换为环绕在其周围的<span>标记样式的
The simplest solution is to use str_replace() to replace the search term with <span> tags wrapped around them, styled.
