Strings that contain variables?

[jshowe]

Hi everyone,
I have a string that is a collection of variables without the $. This is what I have so far but they won't evaluate as variables... Thanks for the help in advanced!

$line="articles,subject,exptime";

$pieces = explode(",", $line);

foreach($pieces as $pieces2)
{
echo "$pieces2<BR>";
}

$values="'$" . implode("','$", $pieces) . "'"; // formats the array containing the form elements for db insertion

echo $values; // Output:  '$articles','$subject','$exptime'

Yeah - I considered doing variable variables but I was told they were sorta looked down apon... Can anyone think of a better way of accomplishing this?

I was told they were sorta looked down apon

By whom? Just out of curiosity.

They're often used when they're not really needed, but they have a lot of legitimate uses.
