Printing Variables

how do you print variable names rather then the content the variable contains?

<?php
$str = "this is inside the variable";

echo $str.' $str';
?>


If you have a variable inside single quotes, it won't parse (if that's the right word) :)

echo "$str";

will show "This is inside the variable"

echo '$str';

will show $str

If you don't know the variable name (for example, you have a an array and are looping through it), it's impossible, but it's probably solvable another way. If Nightfire's method didn't solve your problems, post some code.
