Hello, I am snikolov i am creating a miniwebserver with php and i would like to know how i can send the client a file to download with his browser such as firefox or internet explore i am sending a file to the user to download via sockets, but the cleint is not getting the filename and the information to download can you please help me here,if i declare the file again i get this error in my server
Fatal error: Cannot redeclare openfile() (previously declared in C:\User
s\fsfdsf\sfdsfsdf\httpd.php:31) in C:\Users\hfghfgh\hfghg\httpd.php on li
ne 29, if its possible, i would like to know if the webserver can show much banwdidth the user request via sockets, perl has the same option as php but its more hardcore than php i dont understand much about perl, i even saw that a miniwebserver can show much the client user pulls from the server would it be possible that you can assist me with this coding, i much aprreciate it thank you guys.

Answer 1

You are not sending the filename to the client, so how should it know which filename to use?
There is a drawback, you can provide the desired filename in the http header, but some browsers ignore that and always suggest the filename based on the last element in URL.
For example http://localhost/download.php?help.me would result in the sugested filename help.me in the file download dialogue.
see: http://en.wikipedia.org/wiki/List_of_HTTP_headers

Answer 2

Everytime you run your while (1) loop you declare openfile function. You can declare function only once. Try to move openfile declaration outside loop.
