php - 尝试用 php 编写一个简单的字母表程序

Question

我试图从单行 A-Z 中的数组中吐出字母表中的每个字母。

到目前为止，这是我的代码的样子:

$alphabet = array ("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z");

while ($alphabet) {
   echo $alphabet;
   $alphabet;
}

我有点卡在这部分了，不太确定要写什么才能使它工作。有什么建议吗？

Answer 1

使用range和 array_walk :

function e($s) { echo $s; }
array_walk(range('A', 'Z'), 'e');
