HomeBackend DevelopmentPHP Tutorialphp.ini中,max_input_nesting_level和max_input_vars两个限制如何理解?

我的网站只有一层变量,类似/index.php?a=a&b=b,不会出现/index.php?a[a]=aa&a[b]=ab的情况,个数也不超过2个。

但是经测试只有设置成下面的才不会报错:

<code>max_input_nesting_level=2</code>

首先这个我以为应该是=1,但是只有=2才不会出错;

<code>max_input_vars=36</code>

这个就更奇怪了,我没有那么多参数,为什么要36才不会出错。

以上使用下限我都是从0开始一个个试出来的。

另外,大家认为有必要为了防止用户错误输入路径,而把这个限制设得大一些吗?

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

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),
