I have been very confused. In the document, said the more obscure, is move_uploaded_file this function, added a step check, check whether the file is HTTP POST upload,
As for, how to check the not said.
I google for a while, have not been able to solve the problem, do not know where the problem arises. Later, finally decided to look at the source code. Finally in the source code to see the file name and
PHP configuration in the Upload_tmp_dir this parameter to compare, if the file under this directory, then the move_uploaded_file will be moved operation. And this comparison is case sensitive,/\ is not the same under Windows. And in the PHP configuration file parsing, will call a Realpath function, that is to say, before you move_uploaded_file,
Must be to $file[' tmp_name '] = Realpath ($file [' tmp_name ']); Realpath, please.
There is another situation, we have to note that move_uploaded_file if configured as an inaccessible path, then you do not care, Move_uploaded_file always can not move the file successfully.
The above describes a upload php file upload a problem, including the content of the upload, I hope that the PHP tutorial interested in a friend helpful.
