你好，我想問一個問題，現在我開始使用搜索引擎，所以你可以建議一些函數或方法如何開始或從數據庫用戶製作搜索引擎時使用什麼通過用戶名。它可以從另一個字的一個符號搜索，我寫'k'，然後它搜索所有以用戶名'k'開頭的用戶名。 例子： http://postimg.org/image/sg84ny3w3/php搜索引擎暗示
嘗試：
private function Search()
{
global $database;
if(isset($_POST['s'])) {
if($_POST['s'] == '1' || $_POST['s'] == '2' || $_POST['s'] == '3')
$type = $_POST['s'];
$database->getSearchData($type, $_POST['xs']);
}
else if(!preg_match("/[^0-9A-Za-z]/", $_POST['xs'])){
$error = "You entered invalid data";
}
return false;
}
HTML：
<div id="content">
<div style="padding:20px">
<?echo $error;?>
<form action="index.php?mod=highscore&t=search" method="POST" accept-charset="utf-8">

在發佈數據中搜索％和*，然後將其傳遞給數據庫：其中名稱像$ variable。 「％」 – 2013-04-05 20:04:33
它應該看起來像這樣： 「SELECT * FROM users WHERE username ='$ keyword％''？ – karolis 2013-04-05 20:08:17
