[SOLVED] Is it possible to fake a variable ?

[mega77]

I would like to know if there is any way to fake a variable. In the example below, is it possible to change $email to something else ?

 

 

<?php
$email = "[email protected]";
print $email;
?>

I assume you don't mean by just using "$email = 'something else'", but beyond that I'm not sure what you mean. Fake it on which end? And to one level? Could you explain what you really want to do?

What do you mean? Please explain your question better.

No, with the code you posted it isn't.

 

If there was register_globals turned on and $email wasn't assigned before it was printed, then yes.

 

Example

<?php
// $email was never modified so its the value you give it.
print $email;
// more code;
?>

 

Although, don't depend on register_globals.

This situation is just theoretical.

 

I was just wondering if a surfer-hacker could change that php variable in any possible way. Of course the surfer-hacker would not have access to my server, just surfing.

 

I guess you are right and I'm just being paranoid here. If the variable is already set previously, there is no way...

Unless your retreiving it via $_GET['email'] then nope, if you are it can be forced through www.domain.com/?email=somethingelse

Hope this helped.
