直接使用html5的fileRead,可以传base64数据到后台,后台转文件保存,插件的话Uploadify/uploadifive
建议使用微信的 图像接口uploadImage 然后在拉取到本地服务器
<code> $url ='通过微信api获取到的图片地址'; $filename='图片名称.jpg'; $hander = curl_init(); $fp = fopen($filename,'wb'); curl_setopt($hander,CURLOPT_URL,$url); curl_setopt($hander,CURLOPT_FILE,$fp); curl_setopt($hander,CURLOPT_HEADER,0); curl_setopt($hander,CURLOPT_FOLLOWLOCATION,1); //curl_setopt($hander,CURLOPT_RETURNTRANSFER,false);//以数据流的方式返回数据,当为false是直接显示出来 curl_setopt($hander,CURLOPT_TIMEOUT,60); curl_exec($hander); curl_close($hander); fclose($fp); Return true; </code>
1.楼上所说,用微信提供的图片上传解决方案,优点是兼容所有的手机,缺点是只保存三天,不是永久保存,还需要自己手动拉取回来。
2.百度的web uploader,对手机端上传的兼容性还不错,android 4.3+UC完美使用,但估计还是会有一部分手机中枪用不了。
其实和php关系不大,更多的是看你前端实现。考虑一下base64?

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
