The difference between put and post in php

1. The difference between using support and scope:

PHP provides support for PUT methods. In the method of interaction with the server defined by Http, PUT sends messages from the message ontology to a URL, which is similar to POST in form

PHP provides support for HTTP PUT methods used by clients such as Netscape Composer and W3C Amaya

In PHP 4, you must use a standard input stream to read the contents of a HTTP PUT

The PUT method is not as widely used as the POST method, but the PUT method is the most efficient way to upload files to the server:

2. The difference in the upload process:

When uploading a file by POST, it is usually necessary to combine all the information into multipart, and then the server decodes the information. The decoding process consumes memory and CPU resources, especially when uploading large files.

The PUT method allows you to pass the contents of the file without other information through the socket link established with the server, which is more direct in effect.

3. The difference of upload effect:

When PHP receives a request from the PUT method, it will save the uploaded file to the same temporary directory as other files processed by the POST method; when the request ends, the temporary file will be deleted.

The PHP script used to process PUT must copy the file somewhere else

4. The fundamental difference between POST and PUT requests

The URI requested by POST represents a resource that processes the closed entity, which may be a data receiving process, a gateway to a protocol, or an independent entity that receives comments

The URI in the PUT request indicates the closed entity in the request-the user agent knows the target of the URI

The server cannot apply the request to other resources

If the server wants the request to be applied to another URI, it must send a 301response

The user agent can decide whether or not to forward the request at its own judgment

At this point, I believe you have a deeper understanding of "what is the difference between put and post in php". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
