javascript - Problem with HTML JS passing value to PHP.
Maybe my thinking is not good. What I need to do is to select multiple pictures, click to automatically package the zip, and then download.
ZIP already exists, but PHP doesn’t understand it, so I made a form on the front end to get multiple image addresses to PHP, and then PHP traversed and packaged them into ZIP.
PHP
<code>$imagee = $_GET['pic']; foreach ($imagee as $k => $v) { $image[]= array( 'image_src' =>$v, 'image_name' => mt_rand(1, 1111) . '.jpg' ); } </code>
Originally I wanted to get the specified src through js
js
<code><script> var images = document.getElementsByClassName("1"); var imageStr = ""; for(var i=0;i<images.length;i++){ imageStr+=images[i].src+'/'; } alert(imageStr); </script> </code>
I found that the output is a piece of data, and PHP doesn’t know how to write a loop
Can you help me? Get the image address of the specified class and pass it to the background phpzip for packaging

'.jpg' ); } 我看你这段代码感觉你上传的变量就是一个$_GET['pic'],所以你在前端很可能提交的是一张图片还不是一段图片吧。如果你要提交一组图片,可能参考下下面的方式: 1。<input type="file" name="pic[]" > 这样在后台$_GET['pic']得到的就是一个数组了,可以遍历了。 2。使用js把前台选中的图片地址,json化,然后赋值给<input type="file" name="pic" >再提交表单,或者直接js提交表单。</code>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.
