Auto-Delete Uploaded Files in PHP

In PHP, you can use the unlink() function to delete a file. To automatically remove uploaded files, you can add the code to delete the file after processing the uploaded file.

For example, if the uploaded file is stored in a folder named “uploads,” you can use the following code to delete the uploaded file:

// 获取上传文件的路径
$uploadedFile = $_FILES['file']['tmp_name'];

// 删除上传的文件
if (file_exists($uploadedFile)) {
    unlink($uploadedFile);
}

Please note that this only deletes temporary uploaded files. If you want to delete files that have been moved to a specific directory, you will need to provide the file path for deletion.

It is important to note that deleting a file is irreversible, so handle with caution. It is advisable to perform some conditional checks before deleting a file to ensure that you are only deleting the desired files.
