本文实例讲述了php使用CURL不依赖COOKIEJAR获取COOKIE的方法。分享给大家供大家参考。具体分析如下:
PHP中CURL类是一个非常牛逼的工具类,具体怎么牛逼就不啰嗦了。
对于COOKIE,CURL类也有很不错的支持,但不够灵活,并未能通过现成的方法以变量的方法获取到,而以要通过以下方法实现。
// 把COOKIE保存至cookie.txt curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt'); curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
先把COOKIE保存文件,调用的时候还得读取文件,这样意味着两次的IO操作,效率如何,不用说大家都清楚了。
那么有没有办法可以绕过写读文件呢?不卖关子,直接上代码:
// 初始化CURL $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); // 获取头部信息 curl_setopt($ch, CURLOPT_HEADER, 1); // 返回原生的(Raw)输出 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 执行并获取返回结果 $content = curl_exec($ch); // 关闭CURL curl_close($ch); // 解析HTTP数据流 list($header, $body) = explode("\r\n\r\n", $content); // 解析COOKIE preg_match("/set\-cookie:([^\r\n]*)/i", $header, $matches); // 后面用CURL提交的时候可以直接使用 // curl_setopt($ch, CURLOPT_COOKIE, $cookie); $cookie = $matches[1];
希望本文所述对大家的php程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
