Session upload progress

In PHP, the session-upload-progress extension provides a way to track the progress of file uploads. This extension enables developers to store and retrieve information about the progress of an upload session in the PHP session data.

When a file is uploaded, the extension generates a unique identifier for the upload session and stores it in the session data. The session data is then updated with information about the progress of the upload, such as the number of bytes uploaded and the total size of the file. This information can be accessed by the developer in order to display progress information to the user, or to perform other actions based on the progress of the upload.

To use the session-upload-progress extension, developers must first install and enable it on their PHP server. Once enabled, they can use the provided functions to track the progress of file uploads and retrieve information about the upload session. This information can then be used to provide feedback to the user, or to perform other actions based on the progress of the upload.
