RegExps and values in hash

[Florian Behaim]

Greetings,

Say I got the following:

A hash ($list) with the keys named keyA, keyB, ...
and values associated to them (valueA, valueB).
Furthermore a template with placeholders like {keyA}
.... {keyB} ...

(So the placeholders have the same names as the keys of the hash.)
What I want now, is that the values from the hash are parsed into the
corresponding placeholders.
Say: {keyA} becomes valueA (which is $list['keyA']).

For that purpose I've already done this regular expression:

$Output = preg_replace("=\{(.*)\}=U", $list["$1"], $template);
PROBLEM: There are no values parsed!

Now, what's my mistake and who can help?!
Lots of thanks,
regards Florian Behaim

$Output = preg_replace("=\{(.*)\}=Ue", '$list["$1"]', $template);
// 1 2 2

1: Use the /e modifier to evaluate the replacement string
2: The second parameter should be a literal string
