I. Use php file functions for Upload
This code is divided into two files, one is upload.html and the other is upload. php.
Select Upload File: upload.html code:
<Form enctype = "multipart/form-data" action = "upload. php" method = "post">
<Input type = "hidden" name = "max_file_size" value = "100000">
<Center> select a file:
<Input name = "userfile" type = "file">
<Input type = "submit" value = "Upload file">
* ** Description ***
1. Please note that <form enctype = "multipart/form-data" ......> this is a tag. To upload a file, you must specify it as multipart/form-data. Otherwise, the server will not know what you are doing!
The value of 2xx is the hidden value range of the form option MAX_FILE_SIZE in the file upload.html.
Its Value can limit the size of the uploaded file.
Process the uploaded file: the upload. php code is as follows:
<Title> process uploaded files </title>
Copy ($ userfile, "newfile ");
Echo $ userfile. "-name of the temporary file uploaded to the server <br> ";
Echo $ userfile_name. "-original name of the file on the user's machine <br> ";
Echo $ userfile_size. "-actual number of bytes of the uploaded file <br> ";
Echo $ userfile_type. "-if the user's browser provides this information, it indicates the mime type. For example, image/gif <br> ";
