使用list（）或类似方法实现左侧分配，同时保留除第一个参数外的所有其他参数的数组 [英] Using list() or similar to achieve left-hand assignment while conserving array for all other parameters than the first

问题描述

我知道标题没有透露。如果有解决方案，则可能涉及一些体面的欺骗。

The title doesn't give it away, i know. If there is a solution to this, it probably involves some decent trickery.

情况

我将通过代码进行解释：

I'll explain via code:

$str = 'all.your.base';
list($a, $b, $c) = explode('.', $str);

$ a ， $ b 和 $ c 将进行相应设置。

$a, $b and $c will be set accordingly.

但是，我想要实现的更像是这样：

However, what i want to achieve is more like this:

$str = 'all.your.base';
list($a, $rest) = explode('.', $str);

之后， $ a 应该包含'all'和 $ rest 应该是一个看起来像这样的数组： ['your'， 'base']

Whereas afterwards $a should contain 'all' and $rest should be an array that looks like this: ['your', 'base']

很显然，这可以通过其他方式轻松完成，但是随着我写了几行代码到达那里，我想知道是否没有像我可能没有意识到的解决方案，例如 list（），它可以（通过一些技巧）在较短的时间内提供所需的结果，更快更整洁的方式？

Clearly, this can be done easily by other means, but as i wrote a few lines of code to get there, i was wondering if there is not a solution at hand such as list() that maybe i am unaware of, which can – with some trickery – provide the desired result in a shorter, quicker and neater fashion?

推荐答案

使用第三个参数来爆炸 ， limit

Use the third argument to explode, limit

$str = 'all.your.base';
list($a, $rest) = explode('.', $str, 2);
