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>
