我应该使用php引用转义单引号还是在数组中使用双引号？

I realized that I can have problems with single quotes in php arrays:

我意识到我可以在php数组中使用单引号出现问题：

<?php
$lang = array(
    'tagline' => 'Let's start your project',
    "h1" => "About Me"
);
?>

So I changed it to double quotes:

所以我把它改为双引号：

<?php
$lang = array(
    "tagline" => "Let's start your project",
    "h1" => "About Me"
);
?>

Should I use "php quote escapes", instead of what I just did? (by the way how to write "php quote escapes"?)

我应该使用“php quote escapes”而不是我刚刚做的吗？（顺便说一下如何写“php quote escapes”？）

First of all, some people will say that simple-quoted strings are faster that double-quoted strings ; you should not care about that kind of micro-optimization : it will not make any difference for your application.

首先，有些人会说简单引用的字符串比双引号字符串更快;你不应该关心那种微优化：它对你的应用程序没有任何影响。

The difference between simple-quoted and double-quoted strings is :

简单引号和双引号字符串之间的区别是：

with double-quoted strings, there is variable interpolations
使用双引号字符串，有可变插值
with double-quoted strings, you can use some special characters like \n, \t, ...
使用双引号字符串，您可以使用一些特殊字符，如\ n，\ t，...
with single-quoted strings, you have simple-quotes to escape.
使用单引号字符串，您可以使用简单引号来转义。

For reference, in the PHP manual :

供参考，在PHP手册中：

Single quoted
单引号
Double quoted
双引号

I would that that, in the general matter, it's mostly a matter of personnal preferences...

我认为，就一般而言，这主要是个人偏好的问题......

Personnaly, in a situation such as the one you described, I would use a double-quoted string, like you did : it make the code easier to both write and read, as you don't have to escape that quote.

Personnaly，在你所描述的情况下，我会像你一样使用双引号字符串：它使代码更容易写入和读取，因为你不必逃避该引用。

Do whatever is most readable, assuming you don't need the double-quote special features. For me, that's using whichever quotes for the string that appear the least in the string.

假设您不需要双引号特殊功能，请执行最易读的操作。对我来说，这是使用字符串中出现最少的字符串的引号。
