I am currenty SCping using the command line, where i am asked for the password in order to run the command.

Now I wish to run the SCP command from within a php script. I'd rather enter the password each time in a form rather than store it within the script itself.

How can I handle the password request? i.e., pass the password to the remote system when it asks for it.

PHP has a module to handle SSH2 related activities. Following link explains about sending data using scp; along with a small example. On the same page, hyperlinks with details of other ssh2 functions are provided too.
