关于php数组的操作

1、在foreach循环中如何判断是否已经到数组末尾

<?php
$cars = array("benz" , "audi" , "das auto");
foreach ($cars as $key => $value) {
    if ($value == "das auto") {echo "已经存在"; break;};
    if ($key == count($cars)-1) echo "不存在";
}

2、给数组赋值(不必考虑数组的下标)

foreach ($cars as $value) {
    $cars_news[] = $value;
}
