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
?>
if (!empty($remoteip)){
// 濡

Laravel provides concise HTTP response simulation syntax, simplifying HTTP interaction testing. This approach significantly reduces code redundancy while making your test simulation more intuitive.

The PHP Client URL (cURL) extension is a powerful tool for developers, enabling seamless interaction with remote servers and REST APIs. By leveraging libcurl, a well-respected multi-protocol file transfer library, PHP cURL facilitates efficient execution of various network protocols, including HTTP, HTTPS, and FTP. This extension offers granular control over HTTP requests, supports multiple concurrent operations, and provides built-in security features.
