《PHP实例：PHP中遍历二维数组_以不同形式的输出操作实例》要点：
本文介绍了PHP实例：PHP中遍历二维数组_以不同形式的输出操作实例，希望对您有用。如果有疑问，可以联系我们。
PHP实战如下所示：
PHP实战
<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>
