PHP：我可以引用由函数返回一个数组的单个成员？ [英] PHP: Can I reference a single member of an array that is returned by a function?

问题描述

任何想法如何，如果在PHP以下是可能为单行：

any idea how if the following is possible in PHP as a single line ?:

<?php
$firstElement = functionThatReturnsAnArray()[0];

...这似乎并不拿走。我需要做的这是一个2步进：

... It doesn't seem to 'take'. I need to do this as a 2-stepper:

<?php
$allElements = functionThatReturnsAnArray();
$firstElement = $allElements[0];

...只是好奇 - 其他语言我一起玩允许这样的事情，我很懒惰enoug在PHP错过这个......任何见解AP preciated ...

... just curious - other languages I play with allow things like this, and I'm lazy enoug to miss this in PHP ... any insight appreciated ...

推荐答案

尝试：

<?php
$firstElement = reset(functionThatReturnsAnArray());

如果你只是在寻找数组的第一个元素。

If you're just looking for the first element of the array.
