First look at the instance
| The Code is as follows: |
|
// Determine whether the temporary file storage path contains the File Uploaded by the user
If (is_uploaded_file ($ _ FILES ["uploadfile"] ["tmp_name"]) {
// Store information in variables for higher efficiency
$ Upfile = $ _ FILES ["uploadfile"]; // use an array string to store the information of the uploaded file.
// Print_r ($ upfile ); // If printed, the output is similar to this information Array ([name] => m.jpg [type] => image/jpeg [tmp_name] => C: WINDOWSTempphp1A. tmp [error] = & gt; 0 [size] = & gt; 44905)
$ Name = $ upfile ["name"]; // This parameter can be used to transfer files later.
$ Type = $ upfile ["type"]; // File Upload type
$ Size = $ upfile ["size"]; // size of the uploaded file
$ Tmp_name = $ upfile ["tmp_name"]; // temporary name of the file uploaded by the user
$ Error = $ upfile ["error"]; // error message during upload
// Echo $ name;
// Determine the file type to determine whether to transfer the file. If yes, set $ OK = 1 to transfer the file.
Switch ($ type ){
Case "image/jpg": $ OK = 1;
Break;
Case "image/jpeg": $ OK = 1;
Break;
Case "image/gif": $ OK = 1;
Break;
Default: $ OK = 0;
Break;
}
// If the file meets the requirements and there is no error during the upload Process
If ($ OK & $ error = '0 '){
// Call the move_uploaded_file () function for File Transfer
Move_uploaded_file ($ tmp_name, 'Up/'. $ name );
// After the operation is successful, a message is displayed, indicating that the operation is successful.
