探讨php中遍历二维数组的几种方法详解_php技巧

代码如下:
//使用for循环遍历
$arr2=array(array("张三","20","男"),array("李四","25","男"),array("王五","19","女"),array("赵六","25","女"));
echo "";
for($i=0;$i<4;$i++){
echo "";
for($j=0;$j<3;$j++){
echo "";
}
echo "";
echo "
";
}
echo "

姓名	年龄性别
"; echo $arr2[$i][$j]; echo "

";
?>

//使用foreach遍历
代码如下:
$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']."
";
}
echo "

";
?>

代码如下:
$arr = array('one'=>array('name'=>'张三','age'=>'23','sex'=>'男'),
'two'=>array('name'=>'李四','age'=>'43','sex'=>'女'),
'three'=>array('name'=>'王五','age'=>'32','sex'=>'男'),
'four'=>array('name'=>'赵六','age'=>'12','sex'=>'女'));
foreach($arr as $key=>$value){
foreach($value as $key2=>$value2){
echo $value2;
}
echo "
";
}

?>
