Upload files in php. please take a look. Thank you !!! There is really no way... Help! Html.html & lt; form & nbsp; action = & quot; php. php & quot; & nbsp; method = & quot; post & quot; & nbsp; e php uploads files. Thank you !!!
There is really no way... Help!
Html.html


Php. php
If (move_uploaded_file ($ HTTP_POST_FILES ['userfile'] ['tmp _ name'], 'd:/aaa. avi ')){
Echo "Upload successful! ";
} Else {
Echo "Upload failed! ";
}

During my local testing, I can upload more than 10 MB of files. But when I upload a 38 M file, I cannot upload it ....
And I print var_dump ($ HTTP_POST_FILES ['userfile']); but it is NULL.
I also searched a lot of information on the Internet. The setting values in php. ini have been set, that is, they cannot upload large files.
Several important parameters in my php. ini file are as follows:
File_uploads = On
Upload_max_filesize = 60 M
Post_max_size = 80 M
Max_execution_time= 600
Max_input_time= 600
Memory_limit = 10 M

Hope you can help us to see it ....

------ Solution --------------------
Memory_limit = 10 M... => larger


Var_dump ($ HTTP_POST_FILES ['userfile']);
=>$ _ FILES
------ Solution --------------------
Direct use
$ _ File array.
