使用PHP的`list`函数被认为是不好的做法？

Question

由于列表是一个非常常见的词，因此无法搜索此主题。

list($total, $tax) = $this->getOrderAmounts();

这被认为是不好的做法还是代码味？我觉得我最近一直把它当作一条不好的捷径。

除此之外：list实际上是一种语言结构，而不是一种功能

Answer 1

我个人不会使用列表，因为它是如此＆＃34;不准确＆＃34;。考虑一下： -

$rainbow = array('violet', 'indigo','blue','green','yellow','orange','red');
list($violet,,,,,,$red) = $rainbow;

echo "$violet has low wavelength and $red has highest wavelength"; //Outputs violet has low wavelength and red has highest wavelength

但如果你犯了错误： -

$rainbow = array('violet', 'indigo','blue','green','yellow','orange','red');
list($violet,,,,,$red) = $rainbow;

echo "$violet has low wavelength and $red has highest wavelength"; //violet has low wavelength and orange has highest wavelength

这会更容易： -

$rainbow = array('violet', 'indigo','blue','green','yellow','orange','red');

echo "$rainbow[0] has low wavelength and $rainbow[6] has highest wavelength";
