源自：3-3 案例开发之搜索关键字高亮显示
课程代码:
<?php
$keywrods=isset($_GET['keywrods'])?trim($_GET['keywrods']):'';
$conn=@mysql_connect('127.0.0.3','root','root')or die('连接失败');
mysql_query('use user');//选择数据库
mysql_query('set names utf8');//设置字符编码
//关键词
$sql="select * from user where username like '%{$keywrods}%'";
$rs=mysql_query($sql);//查询结果集
$users=array();//用这个数组保存查询到的数据
if(!empty($keywrods)){//判断传入的数据不为空时,才执行while
while ($row=mysql_fetch_assoc($rs)) {
//对用户名进行关键词高亮
$row['username']=str_replace($keywrods, '<font color="red">'.$keywrods.'</font>',$row['username']);
$users[]=$row;
}
