- <?php
- function results($string)
- {
- $result = array();
- $result[] = $string;
- $result[] = strtoupper($string);
- $result[] = strtolower($string);
- $result[] = ucwords($string);
-
-
- return $result;
- }
- $multi_result = results(‘The quick brown fox jump over the lazy dog‘);
- print_r($multi_result);
- ?>
输出结果：
Array
(
[0] => The quick brown fox jump over the lazy dog
[1] => THE QUICK BROWN FOX JUMP OVER THE LAZY DOG
[2] => the quick brown fox jump over the lazy dog
[3] => The Quick Brown Fox Jump Over The Lazy Dog
)
以上的代码创建了一个$result数组，然后把处理完毕并等待输出的值添加到$result中作为一个元素，最后把$result输出，这样做就实现了自定义函数返回多个值的目的。
