#31341 [NEW]: escape on curly inconsistent
From: nmuhayimana at semanticdesigns dot com
Operating system: Windows NT
PHP version: Irrelevant
PHP Bug Type: Strings related
Bug description: escape on curly inconsistent
Description:
------------
Php suppresses the backslash before left curly brace using
"action at distance", violating the "principle of least surprise".
Apparently the backslash is suppressed if there is any non-escaped dollar
sign any where in the string.
Reproduce code:
---------------
<?php
echo ("$ \{ \n");
echo (" \{ $\n");
echo (" \{$ \n");
echo (" $\{ \n");
echo (" \$\{ \n");
echo (" \{\$ \n");
echo ("\$ \{ \n");
echo (" \{ \$\n");
echo ("% \{ \n");
?>
Expected result:
----------------
$ \{
\{ $
{$
$\{
$\{
\{$
$ \{
\{ $
% \{
Actual result:
--------------
$ {
{ $
{$
${
$\{
\{$
$ \{
\{ $
% \{
