Bug Type: Scripting Engine problem
Operating System: Linux (2.6.14)
PHP Version: 5.1.2
New Comment:
Here is another example to highlight the problem:
php -r '$test = array(array(0,1), array(2,3)); echo
"{$test[1][0]}\n";'
This should produce the following output:
2
php -r '$test = array(array(0,1), array(2,3)); echo
"\{$test[1][0]}\n";'
This produces:
\{Array[0]}
Since curly braces are no longer special characters, should not echo
"\{$test[1][0]}\n"; produce the following?
\2

I disagree, this *is* a bug. You can't have it both ways, either the
curly brace is not a special character and does not need to be escaped,
or it is a special character used for complex variables and can be
escaped. What you have right now is neither ... it's a special
character and removed from the output when used with a complex
variable, but if escaped, it's not used with the complex variable and
additionally the backslash is added to the output.
By the way, my intention was never to produce {$ in the output, but
only to make sure the curly brace was output along with the variable.

this is not a bug, it's a behaviour change of the engine.
see.

and the documentation here:
"Before PHP 5.1.1, backslash in \{$var} hasn't been printed."
"(Use "{\$" to get a literal "{$")." [1]

Description:
------------
When escaping curly braces in a string, the backslash characters are
included in any output.
Reproduce code:
---------------
<?
$test = "test";
echo "\{$test\}\n";
?>
Expected result:
----------------
The above output should be:
{test}
Actual result:
--------------
The actual output is:
\{test\}
