<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"));

The first output form (echo statement)

/* echo "<table width=100% border=&#39;1&#39;>";
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>

The second output form (HTML code table Output)

<body>
<table width=100% border=&#39;1&#39;>
    <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>

The third output form (drop-down list)

<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 $v){
    echo "<option value=&#39;$v[0]&#39;>$v[1]</option>";
};
?>
</select>
</body>

The fourth output form

<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
$arr = array(
    array("1","上海")
);
echo "<option value=&#39;{$arr[0][0]}&#39;>{$arr[0][1]}</option>";
取数组中任意一个数据
$arr = array(
    array("1","台湾"),
    array("2","北京"),
    array("3","上海"),
    array("4","广州"),
    array("5","香港")
);
echo "<option value=&#39;{$arr[4][0]}&#39;>{$arr[4][1]}</option>";
?>
</body>
