PHP no longer replaces {$value} in strings

Question

I am having problem with my PHP coding lately. I used to code like this;

<?php
$value = "ipsum";
echo "{$value} lorem";
?>

Output : ipsum lorem

I don't know what happened but like 10 days / 2 weeks ago the same coding gives me following output;

{$value} lorem

Since this happened, I also can't use <? ?> tags, I have to use <?php ?> tags. I know tags are related to PHP.ini but I have no idea what to edit in PHP.ini to solve my output (echo / print) problem.

EDIT :

My problem is not php short tags. I just meant those 2 problems occurred together so I wanted to write it down. Considering this is the first time I heard and / or experienced such problem, I just wanted to write everything down.

EDIT 2:

My problem is solved after uninstalling / re-installing (2 times, first one didn't help) xampp. I'm accepting Jeremy Banks answer as a solution. Please note that my problem's solution wasn't his answer but I had to chose an answer since there wasn't a possibility to close the question with a real reason.

I know how to fix it. I just meant out of sudden something happened to my php.ini and I got problem with ?> tags along with output problem. — Revenant, Sep 16 '11 at 22:58
Maybe php is using another php.ini. Use phpinfo to see the location... — , Sep 16 '11 at 23:00
No, it is the correct php.ini Come to think once again, I have tried to install newer version of xampp. My system created some small problem didn't want to fix my codes and installed the old version of xampp again. I would think that might be the reason but everything went smooth for a week at least. I am truly lost now. — Revenant, Sep 16 '11 at 23:06
I re-installed xampp (2 times, first one didn't work) and now it is working without any problems. I still don't understand the reason but re-installing helped. — Revenant, Sep 17 '11 at 08:57

By using quoting your strings with ' you're not allowing $variables to be interpolated into it. You need to quote with " for that to work.

<?php
$value = 'ipsum';
echo "{$value} lorem";
?>

It doesn't change anything. I still can't use it. (I'm used to use " " btw) – Revenant Sep 16 '11 at 23:02
Is it possible to turn off interpolation for double quoted strings? – animuson Sep 17 '11 at 00:15
I can use double quoted strings as well as single quoted strings, it just doesn't print variables value. It acts as if {$value} is a string not a variable. – Revenant Sep 17 '11 at 00:54

That <? is short_open_tag. Look for that in PHP.ini That output problem, it's because single quotes doesn't recognize it. change it to double quotes
