我应该使用单引号PHP引号逃逸或阵列使用双引号？ [英] Should I use php quote escapes for single quotes or use double quotes in arrays?

问题描述

我意识到，我可以在PHP数组单引号的问题：

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

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

所以我改成了双引号：

So I changed it to double quotes:

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

我应该使用PHP报价越狱，而不是什么，我只是做了？
（顺便说一下如何写PHP报价逃逸？）

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

推荐答案

首先，有些人会说简单引用的字符串会更快的双引号字符串;你不应该在乎那种微优化：它不会让你的应用程序的任何区别

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.

结果
简单引用和双引号字符串之间的区别是：

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

• 用双引号字符串，有可变插值


• 用双引号字符串，就可以使用一些特殊的字符，如 \\ n ， \\ t ..


• 用单引号字符串，你有简单的报价逃脱。

有关参考，在PHP手册：

For reference, in the PHP manual :

• 单引号


• 双引号

• Single quoted
• Double quoted

结果
我会说，在一般的问题，它是主要的personnal preferences的问题...

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

Personnaly，在一个情况下，如你所描述的，我会用一个双引号字符串，像你这样的：它使code更容易写和读，因为你没有逃跑该报价。

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.
