How do I retrieve a mobile phone id

Hi All,

Has anyone got any ideas on how to retrieve mobile phone info from a phone
that connects to my web site, I want to use that data as part of logon
authentication, for example:

<?php
$user_agent = $_SERVER["HTTP_USER_AGENT"];
?>
The info from your mobile is <?php echo($user_agent ); ?>

will give me info such as

Nokia 6060/2.0(5.11)
Profile/MDP-2.0
Configuration/CLDC-1.1

I would like to retrieve the phone number of the phone and any other id data
thats available.

Any ideas?

Any suggestions are gratefuly recieved!

You are kidding, right?

Would you also like the phone owners name and address, perhaps their bank
account details?

Think about *privacy*.

OK to be more explicit. Bottom line: you don't. Unless the phone's
browser gives you the number, you're SOL. Figure out some other way.

Hi Richard,

Perhaps I should explain, the user of the site, who will be the owner of the
phone will have volunteered that data in the first place, I just want to be
able to check that it is that actual phone that is logging on, this data is
available throught HTTP Headers from the phone. I do agree with you on the
privacy issue.

Thanks anyway

There are alternative, better ways for authorizing the user.

No, it isn't. And even if it were, do you realize how easy it is to open
pages with php and write custom headers. Say I want to hack in your
system. Fine, I'll just open a socket with fsockopen, write the headers,
insert your phone number in the headers and chi-ching, you're pwend.
Secure? I don't think so, Tim.

Then you'll understand why it isn't in the headers. What makes you think
it would be?

If you don't believe me, just echo the entire header to see for
yourself. <?php print_r(getallheaders()); ?> If the phone number was
there, please let me know...
