Eval? Hmm. Var names.

Hi there,

I am trying to change var names like so:

    for ($i = 0; $i < $noOfShows; $i++)
    {
        $varname$i;
    }

So that $varname, becomes $varname1, $varname2 etc etc.

I think it's something to do with eval() but I can't figure it out. Any help much appreciated!

Cheers,

Mike

try replacing '$varname$i' with '$varname .= $i'. this is basically the expanded form of $varname = $varname . $i

The '.' acts as the concatenation operator.

Might work, give it a go. hope this helps.

sorry, ignore that, i misundrestood your post. :o will think about it.


for ($i = 0; $i < $noOfShows; $i++) 
{ 
${'varname'.$i} = 0; 
}

That will do what you need.

Thanks for all your help guys.

Chimera, that worked a treat.

do you know how to use arrays?!?!? there is no reason you should ever have to do this.

Yes, I know how to use arrays. There is a reason for me to be doing this otherwise I wouldn't be asking.
