探讨php中遍历二维数组的几种方法详解

复制代码 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 "

& gt;";
for($i=0;$iecho "";
for($j=0;$j   echo "";
}
echo "";
echo "
";
}
echo "

姓名	年龄	性别
";    echo $arr2[$i][$j];    echo "

";
?>

//使用foreach遍历

复制代码 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 "

";
?>

复制代码 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 "
";
}

?>
