PHP中遍历二维数组_以不同形式的输出操作实例

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>
