在PHP关联数组索引中使用空格是否不好？ [英] Is it a bad practice to use spaces in PHP associative array indexes?

问题描述

我必须使用关联数组传递一些参数，例如：

I have to pass some parameters using an associative array, something like this:

$blockGroup['name=products type=complete']

做一些测试，我发现它可行，但这是一个不好的做法吗？可能会产生任何错误或意外行为吗？

Doing some tests i saw that it works, but is it a bad practice? Is it possible to generate any bug or unexpected behavior?

感谢任何建议！

我在视图实现中使用此数组，完整结构为：

I am using this array in a view implementation, the complete structure is:

$blockGroup['name=products type=complete'][] =
    array(
        'name'  => 'GeForce',
        'value' => '99.99'
    );

推荐答案

不，不是。编程中的空格符号实际上并没有特殊含义。括在引号中并因此形成字符串的符号可以用作关联数组键。

No, it's not. Space symbol in programming doesn't really have a special meaning. Symbols enclosed in quotes and thus forming a string can be used as associative array keys.

实际上，很多时候将此类键用于关联数组会使

In fact, there are a lot of times when using such keys for associative arrays will make your code readable and handy to make changes to it.

$scores = array("John Doe" => 100, "Ivan Ivanovich" => 75.3);

我看到的是您试图使用数组键作为表达式，这确实是一个坏习惯。事情是为了他们的意图。使用关联键作为关联键。

What I see is you trying to use array keys as an expression, which is REALLY bad practice. Things are meant for what they meant for. Use associative keys as associative keys.
