HTTP programming help

gabidi

Hi,

In my next project, i need the user to upload a file to my site via a regular php form.

I then need the php program to connect to website (outside my network) upload the file there. That site would then validate if the the file is valid and i would echo the result on my script page, and if it's not valid i would also echo that on my site.

Now i know how to write everything for upload, validating, parsing and echoing, i'm just in need of help on how to connect to another website and "listen to the reponse" .

I need all this to take place without the client's browser knowing it. I.E all the client sees is a request uploading the file and then the responce on my site.

Is it possible ? If any good "http" or "socket" programming tutorials are out there, i would greatley apprecaite you pointing it out .

(Sadly the PHP book i invested in , included everything i need to know besides socket programming)

Thank you for this great forum and looking forward to your replies

you can use the php network functions to open socket connections and pass data to another site.
http://www.php.net/manual/en/function.fsockopen.php
is a good place to start reading on it. you can simulate an http post and pass the data as x-www-form-urlencoded. cURL is also an easy alternative to simulate http requests.

Hi Drew,

Thank you very much for your reply, it was exactly what i needed and infact i'm almost done setuping up the whole script.

I have one more question.

The site to which i upload the files to be analyzed requires an HTTP user name and password authroization (Apache server) .
I would like my script to authorize it's self, and then continue to upload and all that.

Naturally i dont want the client to see the user name/password nor to be aware of the redirection (would like it to be totally server sided), and therein lies the problem.

Any help with that would be greatley apprecatied.

Once again thank you very much for your time and help
