Variable number of variables?

[Anon]

Suppose I have a form that itself has a variable number of fields, with each field labeled as "id1", "id2", "id3"....

How would I retrieve these in the PHP file that receives this information?

I tried $id.$i, where $i is the number in the loop, and $id is the id of the field.

basically, what I want to know is is there a way to arbitrarily access a variable, who's name is the combination of the values of two or more other variables?

ie. access $foo2, where $i="foo" and $j="2"

thanks in advance!

Try the following:

to access $foo2 where $i="foo" and $j="2" use the following syntax:

${$i.$j} ... this will get $foo2

or, if you want $id1, 2, 3 etc do
${"id".$i} where $i is the number.

Hope that helps!
