Description:
------------
Hello,

I have slaved over this one line of code and confirmed that there is absolutely nothing wrong with it. I have even modified it and received the same error. The error even persists when the line is commented out.

I receive a parse error as well as a warning for the backslash.

Reproduce code:
---------------
<?php
 $contents = "<?php\r\n \$galleryDesc = \"".addslashes($galleryDesc)."\";\r\n";
?>

Expected result:
----------------
I expected the value of $contents to be:
<?php
 $galleryDesc = "...";


Actual result:
--------------
Warning: Unexpected character in input: '\' (ASCII=92) state=1 in ... on line ...

Parse error: syntax error, unexpected T_STRING in ... on line ...
