Getting data from data in PHP

[Anon]

I have a value stored in $value1 for example. Then, I call value1 in a loop and name it the value $dataval. Here is the code:

$i = 0
while ($dataval = value$i)
{
$i += 1;
}

However, I need that data that is stored in $value1. How can I get this value through $dataval?

Something like $ .= $dataval.....please help

have you tried using variable variables?...there is a good article at http://www.phpbuilder.com/columns/robert20000928.php3 on the subject...

I'm not sure that I understand your question, but I think you want to loop through a bunch of variables all named $valueN (where N is an integer) and put each value into a separate variable called $dataval. If so this code should work:

$i=0;
$temp_name = "value$i";
while ($dataval = $$temp_name) {
$i++;
$temp_name = "value$i";
}

You need to use a variable variable name which is what the $$ operator does.
