1.實(shí)現(xiàn)分頁(yè)功能
<body>
<table width="100%" border="1">
<thead>
<tr>
<th>代號(hào)</th>
<th>名稱</th>
<th>價(jià)格</th>
</tr>
</thead>
<tbody>
<?php
require_once "./DBDA.class.php"; //加載數(shù)據(jù)庫(kù)訪問類的封裝文件
require_once "page.class.php"; //加載分頁(yè)類的封裝文件
$db = new DBDA();
$sql = "select count(*) from car";
$arr = $db->query($szts);
$page = new Page($arr[0][0],5); //查看總數(shù)據(jù)，并每頁(yè)顯示的行數(shù)據(jù)
$sql = "select * from car".$page->limit; //拼接每頁(yè)顯示的數(shù)據(jù)
$arr = $db->query($sql);
foreach($arr as $v){
echo "<tr>
<td>{$v[0]}</td>
<td>{$v[1]}</td>
<td>{$v[2]}</td>
</tr>";
}
?>
</tbody>
</table>
<div style="margin-top:20px">
<?php
echo $page->fpage(); //調(diào)用分頁(yè)類的方法
?>
</div>
</body>
2.實(shí)現(xiàn)多條件查詢功能
<body>
<?php
require_once "./DBDA.class.php";
require_once "page.class.php";
$db = new DBDA();
//做一個(gè)恒成立的條件
$tj = " 1=1 ";
$tj2 = " 1=1 ";
$name = " ";
$brand = " ";
//當(dāng)提交的數(shù)據(jù)不為空，需要改條件
if(!empty($_GET["name"])){
$name = $_GET["name"];
$tj = " name like '%{$name}%' "; //使用模糊查詢查詢關(guān)鍵信息
}
if(!empty($_GET["brand"])){
$brand = $_GET["brand"];
$tj2 = " brand = '{$brand}' ";
}
?>
<table width="100%" border="1">
<form action="test.php" method="get">
<input type="text" name="name" placeholder="請(qǐng)輸入名稱" value="<?php echo $name ?>" style="max-width:200px; float:left">
<input type="text" name="brand" placeholder="請(qǐng)輸入系列" value="<?php echo $brand ?>" style="max-width:200px; float:left">
<button type="submit" style="float:left; margin-left:10px">查詢</button>
</form>
<thead>
<tr>
<th>代號(hào)</th>
<th>名稱</th>
<th>系列</th>
<th>時(shí)間</th>
<th>價(jià)格</th>
</tr>
</thead>
<tbody>
<?php
$zts = "select count(*) from car where {$tj} and {$tj2}"; //多條件查詢數(shù)據(jù)總數(shù)
$ats = $db->query($arr);
$page = new Page($ats[0][0],2);
$sql = "select * from car where {$tj} and {$tj2} ".$page->limit;
$arr = $db->query($sql);
foreach($arr as $v){
//給查詢的關(guān)鍵字加字體顏色
$n = str_replace($name,"<span style='color:red'>{$name}</span>",$v[1]);
echo "<tr>
<td>{$v[0]}</td>
<td>{$n}</td>
<td>{$v[2]}</td>
<td>{$v[3]}</td>
<td>{$v[7]}</td>

}
?>

<div>
<?php
