HomeBackend DevelopmentPHP Tutorial一个简单的php在线端口扫描器

作者:angel

前言

php是一种功能强大的Web开发语言。开发效率高,语法简单,为动态网站量身定做,加强面向对象(向C++靠拢,与java搭了点边),可惜单线程(这是至命弱点,据说PHP是用C\C++编写的。),也能用C、C++、JAVA开发中间层,调用COM,服务器维护难度小,故障少。

既然是为动态网站量身定做,所以注定不能开发出X-scan这样的超强扫描器,不过如果要实现一些简单的功能,还是绰绰有余的。

端口扫描是我们最常用的踩点手段。如果在网吧这种地方,下载一个专门的扫描器又比较麻烦,如果利用现有的Web服务提供的端口扫描。那可真的是省了不少事。

下面我们就看看我写的这个PHP端口扫描器的源代码:


$youip=$HTTP_SERVER_VARS["REMOTE_ADDR"]; // 获取本机IP地址

$remoteip=$HTTP_POST_VARS['remoteip']; // 获取表单提交的IP地址

?>

端口在线检测


if (!empty($remoteip)){

// 濡

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),
