http - How to obtain the file content when transferring files via PHP PUT?

Recently, because of the separation of front-end and back-end, all APIs in the back-end PHP use RESTFul style.

But when using PUT to upload files, it was found that $_FILES had no file information (temporary files may not have been uploaded, to be verified). It is ok to use POST, and PUT is obtained from the standard input stream The incoming data is read in the following format (I guessed that the temporary file was not uploaded above because the standard input stream contains file information), and needs to be parsed separately.

Currently I have two ideas:

1. If uploadtemporary files (this is being tested...): If uploaded, temporary files can be read.

2. If does not upload the temporary file: try to parse this string of parameters passed by form-data, but I don’t know if there is a corresponding method for parsing this format php.

By the way, there are often problems when using RESTFul:

1. When it comes to cross-domain, ordinary forms (GET, POST) are fine, but when using PUT, DELETE, you need to set cross-domain headers.
   PS: I don’t understand, why is it needed?

2. MDN HTTP Method document does not have detailed introduction to PUT, DELETE...

3. PHP needs to get PUT, DELETE to file_get_contents('php://input');to get parameter information. There are no global variables like $_PUT, $_DELETE.

Go to stackoverflow and browse around, and find that many people have encountered the same problem, but I haven’t seen a better solution yet.

In addition, in this article jquery ajax put file, php save file, the blogger and I encountered the same problem, but he parsed and processed the data by using regular rules.

I was wondering if there is a better solution that can imitate PHP in handling POST requests, parse the form-data string, and save the ordinary parameters to $_PUT($_POST) , transfer the file to the temporary directory, and then return the file information to $_FILES.

This blog post talks about how to upload files using the multipart/form-data format. It talks about the form-data format.

For now, let’s simply write a composer component that parses form-data.

PHP’s global variable $_FILES can only obtain files uploaded by post. If you want to use put to upload files, you must handle the stream yourself

For mobile phones, the current mainstream is get+post+json

4, standard form data upload format

php put needs to be parsed separately, and put is generally used to accept data in json format

Thank you for your answer. In addition, the question has been re-edited:)
