width oct 信息 eight where main 添加 pre values
一、增加數據
用bootstrap做
<link href="bootstrap.min.css" rel="stylesheet" type="text/css" />
<script src="bootstrap.min.js"></script>
<script src="jquery-1.11.2.min.js"></script>
然後訪問數據庫
<body>
<table class="table table-striped">
<caption>人員信息展示</caption>
<thead>
<tr>
<th>代號</th>
<th>姓名</th>
<th>性別</th>
<th>民族</th>
<th>生日</th>
</tr>
</thead>
<tbody>
<?php
$a = new MySQLi("localhost","root","123456","crud");
if(mysqli_connect_error()){
echo "錯誤";
}
$sql = "select info.code,info.name,sex,nation.name,birthday from info,nation where info.nation=nation.code";
$result = $a->query($sql);
if($result){
$attr = $result->fetch_all();
foreach($attr as $v){
$sex = $v[2]?"男":"女";//三元運算 把性別的1/0（1為ture 0為false）改為男女
echo "<tr>
<td>{$v[0]}</td>
<td>{$v[1]}</td>
<td>{$sex}</td>
<td>{$v[3]}</td>
<td>{$v[4]}</td>
</tr>";
}
}else{
echo "出錯";
}
?>
</tbody>
