$0 -> $100 with $0 etc as variables...

[Anon]

In a form I send some variables through as

$0 , $1 etc

A user can change one of them, and they are known as $nr (for instance $nr = 1) etc.

So when the form has processed, I want the system to do a loop, checking if $1 is in fact $$nr ($1)

But I get an error message.

How do I fix it?

Not sure you can have variables starting with numbers. It works with ASP but PHP seems worth learning.

Used to name for elements 001, 002, etc..

now I use f001, f002, etc.

to read the variable portion you can read

substr($f001,1,3);

this will give you the numerical portion 001.

HTH.

You should be getting an error that looks a little like this
Parse error: parse error, expecting T_VARIABLE' or'$''
That is because I do not think you can start a variable name with a number. Try adding an underscore _ before the number.
