No.

Okay, after "su $user" you may get an error rather than a password prompt.
So now you'd have to parse the output.  Is the output written to standard
error, standard out, or to the tty?  Do we have a tty to read/write to?
Now you have the prompt, and you want to send the password.  Again, do 
you send it to standard input or to the tty?  And how -- via a pipe might
work for standard input, not not from a tty.  php calls like exec() and
system() aren't exactly interactive...  I don't see anyway to do this kind
of thing.  Normally you get around such problems by using a program like
"expect" but that makes things way to complicated now as they would have
possibly install and configure expect...

See my problem?

"TAD (Technology Attachment Disorder) is an unshakable, impractical devotion
to a brand, platform, product line, or programming language. It's relatively
harmless among the rank and file, but when management is afflicted the damage
can be measured in dollars. It's also contagious -- someone with sufficient
political clout can infect an entire organization."
