如下所示:

<body>

<?php 
//定义二维索引数组
$arr = array(
 array("101","李军","男","1976-02-20","95033"),
 array("103","陆君","男","1974-06-03","95031"),
 array("105","匡明","男","1975-10-02","95031"),
 array("107","王丽","女","1976-01-23","95033"),
 array("108","曾华","男","1977-08-01","95033"),
 array("109","王芳","女","1975-02-10","95031")
);
第一种
输出形式(echo语句) /* echo "<table width=100% border='1'>"; echo "<tr><td>Sno</td><td>Sname</td><td>Ssex</td><td>Sbirthday</td><td>Class</td></tr>"; foreach($arr as $v){ echo "<tr><td>{$v[0]}</td><td>{$v[1]}</td><td>{$v[2]}</td><td>{$v[3]}</td><td>{$v[4]}</td></tr>"; } echo "</table>" ; </body> 第二种输出形式(HTML代码 表格输出) <body> <table width=100% border='1'> <tr> <td>Sno</td> <td>Sname</td> <td>Ssex</td> <td>Sbirthday</td> <td>Class</td> </tr> <?php foreach($arr as $v){ echo "<tr> <td>{$v[0]}</td> <td>{$v[1]}</td> <td>{$v[2]}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <tr>"; }; ?> </table> </body> 第三种输出形式(下拉列表) <body> <?php $arr = array( array("1","山东"), array("2","北京"), array("3","上海"), array("4","广州"), array("5","香港"), array("6","澳门") ); ?> <select id="nation"> <option value="all">请选择</option> <?php foreach($arr as $v){ echo "<option value='$v[0]'>$v[1]</option>"; }; ?> </select> </body> 第四种输出形式 <body> 取数组中输出的总数 $arr = array( array(4) ); echo $arr[0][0]; 取数组中一组数据 $arr = array( array("1","上海") ); echo "<option value='{$arr[0][0]}'>{$arr[0][1]}</option>"; 取数组中任意一个数据 $arr = array( array("1","台湾"), array("2","北京"), array("3","上海"), array("4","广州"), array("5","香港") ); echo "<option value='{$arr[4][0]}'>{$arr[4][1]}</option>"; ?> </body>
