FTP Site

Hi,



I'm building a site for a client that has a need to allow their users to
upload large files (up to 100mb or more) and store them on the server. I've
never had a need to work with PHP's FTP functions until now and, before I go
reading the manual to learn how, I wanted to see if this something that I
can handle with just PHP, or if I'm going to need to adopt a third party
Ajax app or something like that? Any thoughts or even a point in the right
direction would be greatly appreciated. Thanks,



Ben

Flash or Java are the best way to go for this. The browser isn't good
for large file uploads, I've had too many fail when the files got too
large, even when the server was set up to allow them.

The PHP FTP functions are for client access to a remote server, not so
that PHP can act as an FTP server. To resolve the issue you'll have to
either give them FTP access, SSH access, or allow huge uploads. If you
insist on doing it via PHP, you can use a .htaccess configuration in the
directory containing the upload script to override the upload/post
maximum sizes for PHP. Similarly, you'll need to increase max execution
time. Since these are clients, I presume they have been authenticated
first (otherwise you're opening yourself up to DoS). Alternatively you
could use a Flash plugin or Java applet to facilitate the upload.

Cheers,
Rob.

Re: FTP Site

I think you will need the help from a client side app, like java
applet or flash, php can transfer file from your web server to your
ftp server but people will have difficulty uploading file via bare
browser

You might want to look at how the mozilla add-on firefogg does it.
They have server code example for php.

Basically it splits the file up into chunks (as it encodes it but
encoding isn't your concern) and when a chunk is received, message is
sent back to the client telling the client it is OK to send the next chunk.

It may be dependent upon browser functionality though, since it is the
browser that splits the large upload into smaller manageable chunks.
