<?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/>";}?>
