PHP Form variables

[Anon]

HELP..

Given the following form;

<form name="f1" action="test.php">
<input type="checkbox" name="cb1" value="1">
<input type="checkbox" name="cb2" value="2">
<input type="checkbox" name="cb3" value="3">
</form>

In PHP $cb1, $cb2, $cb3 gives you the values of cb1,cb2, and cb3 respectively.

I want to pass the name of the checkbox variable into a function and inside the function i would like to instantiate the variable..much like the eval() function in Javascript.

foo( $var ){
...
...
}

foo("cb");

Is this possible?

tks,
art

There is an 'eval()' in php, too, or you could use $$variable.
But to be honest, I don't really understand the question :-)

Thanks Roel...let me try it using eval().
