本文实例讲述了PHP使用curl模拟post上传及接收文件的方法。分享给大家供大家参考,具体如下:
public function Action_Upload(){ $this->path_config(); exit(); $furl="@d:\develop\JMFrameworkWithDemo.rar"; $url= "http://localhost/DemoIndex/curl_pos/"; $this->upload_file_to_cdn($furl, $url); } public function upload_file_to_cdn($furl,$url){ // 初始化 $ch = curl_init(); // 要上传的本地文件地址"@F:/xampp/php/php.ini"上传时候,上传路径前面要有@符号 $post_data = array ( "upload" => $furl ); //print_r($post_data); //CURLOPT_URL 是指提交到哪里?相当于表单里的“action”指定的路径 //$url = "http://localhost/DemoIndex/curl_pos/"; // 设置变量 curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);//执行结果是否被返回,0是返回,1是不返回 curl_setopt($ch, CURLOPT_HEADER, 0);//参数设置,是否显示头部信息,1为显示,0为不显示 //伪造网页来源地址,伪造来自百度的表单提交 curl_setopt($ch, CURLOPT_REFERER, "http://www.baidu.com"); //表单数据,是正规的表单设置值为非0 curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 100);//设置curl执行超时时间最大是多少 //使用数组提供post数据时,CURL组件大概是为了兼容@filename这种上传文件的写法, //默认把content_type设为了multipart/form-data。虽然对于大多数web服务器并 //没有影响,但是还是有少部分服务器不兼容。本文得出的结论是,在没有需要上传文件的 //情况下,尽量对post提交的数据进行http_build_query,然后发送出去,能实现更好的兼容性,更小的请求数据包。 curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); // 执行并获取结果 curl_exec($ch); if(curl_exec($ch) === FALSE) { echo "<br/>"," cUrl Error:".curl_error($ch); } // 释放cURL句柄 curl_close($ch); echo "aaa45"; } function action_curl_pos(){ var_dump($_FILES); $aa= move_uploaded_file($_FILES["upload"]["tmp_name"], "/wamp/tools/1.rar"); if($aa){ echo "11"; } }

希望本文所述对大家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.
