Question

请使用foreach循环遍历数组$ar = array("a","b","c","d","e"); 输出数组中的值

输出数组中的值要求写出有键名和无键名两种模式）

Answer 1

无键：
$ar = array("a","b","c","d","e");
foreach($ar as $key=>$value){
echo '<br>'.$value;
}
有键名：
$ar = array("a","b","c","d","e");
foreach($ar as $key=>$value){
echo '<br>第'.$key.'值是：'.$value;
}
应该是这个意思吧！？
