There are severals bugs about this and I would like some clarification.
http://bugs.php.net/bug.php?id=35527
http://bugs.php.net/bug.php?id=37263
Reproduce:
---------------
<?php
$string="abc";
echo "... {$string} ...\n";
echo "... \{$string} ...\n";
?>
PHP4:
------
... abc ...
... {abc} ...
PHP 5.1.2:
-----------
... abc ...
... \{abc} ...
===============
Now, I can see changing it so that {} is not escapable. However, it is
being escaped. The {} are not being evaluted with the variable in
5.1.2. However, the \ is being left in the string. IMO, you can't have
it both ways.
I expect from PHP5:
--------------------
... abc ...
... \abc ...
Also, this is not listed in the upgrade notes at all
http://www.php.net/README_UPGRADE_51.php.
Thanks,
