二维数组的创建与遍历（php）

<?php
/*for循环遍历*/
$arr = array( array("张三","20","男"),array("李四","25","男"),array("王五","19","女") );
for($i=0;$i<3;$i++)
{
	for($j=0;$j<3;$j++)
	{
		echo $arr[$i][$j]." ";
	}
	echo "<br/>";
}

/*foreach循环遍历*/
$arr = array('1'=>array('name'=>'张三','year'=>'20','sex'=>'男'),
              '2'=>array('name'=>'李四','year'=>'25','sex'=>'男'),
			  '3'=>array('name'=>'王五','year'=>'19','sex'=>'女') 
             );
			 foreach($arr as $key => $link)
			 {
				 echo $link['name'].$link['year'].$link['sex']."<br/>";
			 }

/*foreach*/
$arr = array(  '1'=>array('name'=>'张三','year'=>'12','sex'=>'男'),
               '2'=>array('name'=>'李四','year'=>'12','sex'=>'男'),
			   '3'=>array('name'=>'王五','year'=>'13','sex'=>'女')
			 );
    foreach($arr as $key => $link)
	{
		foreach($link as $key1 => $val)
		{
			echo $val." ";
		}
		echo "<br/>";
	}
 

?>
           

<?php
$arr = array('0'=>'a','1'=>'b','2'=>'c');
for($i=0;$i<count($arr);$i++)
{
	echo $arr[$i]."<br/>";
}

?>
           

<?php
/*list()和each()遍历数组*/
$arr = array('0'=>'张三','1'=>'李四','2'=>'王五');
//使用list()函数获取each()函数中返回数组的值，并分别赋给$num,$name两个变量，然后用while输出
while(list($num,$name)=each($arr))
{
	echo $num.' '.$name."<br/>";
}
