curl_setopt($ch, CURLOPT_POST, 1);
$request = 'username=xxx&pwd=xxx';
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);//传递数据
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);//把返回来的cookie信息保存在$cookie_jar文件中
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//设定返回的数据是否自动显示
curl_setopt($ch, CURLOPT_HEADER, false);//设定是否显示头信息

$orders = curl_exec($ch2);

curl_close($ch2);// 实践证明很稳定:)

先在本机测试,在php.ini中去掉了extension=php_curl.dll前面的;,查看一下phpinfo(),并没有curl。
查了下文档,
复制代码 代码如下:
Note to Win32 Users: In order to enable this module on a Windows environment, libeay32.dll and ssleay32.dll must be present in your PATH.
将libeay32.dll 和ssleay32.dll复制到system32下,重启apache,刷新phpinfo(),看到了curl。
引用
复制代码 代码如下:
cURL support enabled
cURL Information libcurl/7.16.0 OpenSSL/0.9.8d zlib/1.2.3
本机测试顺利通过,再去服务器上测试。原没装curl,只好重新编译php。
在原编译参数后面加了--with-curl=/usr/local/curl。
我这次的配置是:
复制代码 代码如下:
./configure '--prefix=/usr/local/php5' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql=/usr/local/mysql' '--with-gd=/usr/local/gd' '--with-zlib' '--with-png' '--with-jpeg-dir=/usr/local/jpeg' '--with-freetype-dir=/usr/local/freetype' '--enable-sockets' '--with-iconv' '--enable-mbstring' '--enable-track-vars' '--enable-force-cgi-redirect' '--with-config-file-path=/usr/local/php5/etc' --with-curl=/usr/local/curl
很快OK。phpinfo显示

感觉挺好用的:)

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
