<?php
$cars = array("porsche","BMW","Volvo");
$num = count($cars);
for($i=0;$i<$num;$i++){
echo $cars[$i],"<br>";
}
echo "<hr>";
$k = 0;
while ($k < $num){
echo $cars[$k],"<br>";
$k = $k + 1;
}
echo "<hr>";
foreach ($cars as $value){
echo $value,"<br>";
};foreach最为简单，适合遍历数组。

老师总结：完成的不错。for和while是计算循环，foreach是数组循环。继续加油。
