php中遍历二维数组的几种方式

<?php

//使用for循环遍历

$arr2=array(array("张三","20","男"),array("李四","25","男"),array("王五","19","女"),array("赵六","25","女"));

echo "<table border=2
bordercolor=red><tr><td>姓名</td><td>年龄</td&
gt;<td>性别</td></tr>";

for($i=0;$i<4;$i++){

echo "<tr>";

for($j=0;$j<3;$j++){

echo "<td>";

echo $arr2[$i][$j];

echo "</td>";

}

echo "</tr>";

echo "<br>";

}

echo "</table>";

?>

//使用foreach遍历

<?php

$arr = array('one'=>array('name'=>'张三','age'=>'23','sex'=>'男'),

'two'=>array('name'=>'李四','age'=>'43','sex'=>'女'),

'three'=>array('name'=>'王五','age'=>'32','sex'=>'男'),

'four'=>array('name'=>'赵六','age'=>'12','sex'=>'女'));

foreach($arr as $k=>$val){

echo $val['name'].$val['age'].$val['sex']."<br>";

}

echo "<p>";

?>

<?php

$arr = array('one'=>array('name'=>'张三','age'=>'23','sex'=>'男'),

'two'=>array('name'=>'李四','age'=>'43','sex'=>'女'),

'three'=>array('name'=>'王五','age'=>'32','sex'=>'男'),

'four'=>array('name'=>'赵六','age'=>'12','sex'=>'女'));

foreach($arr as $key=>$value){

foreach($value as $key2=>$value2){

echo $value2;

}

echo "<br>";

}

?>
