課程代碼:

$conn=@mysql_connect('127.0.0.3','root','root')or die('連接失敗');
mysql_query('use user');//選擇數據庫
mysql_query('set names utf8');//設置字符編碼
//關鍵詞
$sql="select * from user where username like '%{$keywrods}%'";
$rs=mysql_query($sql);//查詢結果集
$users=array();//用這個數組保存查詢到的數據
if(!empty($keywrods)){//判斷傳入的數據不為空時,才執行while
while ($row=mysql_fetch_assoc($rs)) {
//對用戶名進行關鍵詞高亮
$row['username']=str_replace($keywrods, '<font color="red">'.$keywrods.'</font>',$row['username']);
$users[]=$row;
}
}
