php数组元素的遍历

<?php//定义一个数组$arr = array(0=>"zero", 1=>"one", 2=>"two");//使用第一种方法对数组进行遍历foreach ($arr as $value) { echo "Value: $value; ";}echo "<BR>";//使用第二种方法对数组进行遍历foreach ($arr as $key => $value) { echo "Key: $key; Value: $value; ";}?>  

<?php//定义数组$array = array("ar1" => array(5=>100, 3=>120, 4=>30),"ar2" => array(4=>"three", 9=>"four", 1=>"five"));//对数组进行遍历foreach ($array as $v1) { foreach ($v1 as $v2) { print "$v2/n"; }}?>
