HomeBackend DevelopmentPHP TutorialLet json_encode not automatically escape slash '/' in PHP

前言

最近将使用爬虫爬取的链接保存到 mysql 数据库中时,发现我将链接使用 json_encode 保存时候,在数据库中却显示了转义字符,我并不需要这转义的,看起来不清晰而且占用存储空间。

后来发现在默认的情况之下使用 json_encode 对数组进行 json 格式的转换时候会自动的将数据中含有斜杠的字符串进行转义,但是我们往往有的时候不需要药对它们进行转义的,本文说说如何使用 json_encode 不自动转义斜杠。

对于如下数组 $a,现有两种办法解决:

$a = array(
 'http://www.baidu.com',
 'http://www.baidu.com',
 'http://www.baidu.com',
 'http://www.baidu.com',
 'http://www.baidu.com'
);

其一,正则替换:

$a = str_replace("\\/", "/", json_encode($a));
var_dump($a);

其二,若 php 版本是 5.4 及以上的话:

var_dump(json_encode($a,JSON_UNESCAPED_SLASHES));

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
