Whoa! Why? That seems backwards. If PHP is going to interpret
here files you need to provide an option that allows them to be read
as-is. In many cases we don't have control over the contents of a
here file (I don't in this case), just its placement within the PHP
file. Ergo, if that here file happens to contain backslashes you're
screwed.
Bash takes a useful approach that you may wish to emulate. Quoting
from the manpage:
--<cut>--
The format of here-documents is as follows:
<<[-]word
here-document
delimiter
No parameter expansion, command substitution, arithmetic
expansion, or pathname expansion is performed on word. If
any characters in word are quoted, the delimiter is the
result of quote removal on word, and the lines in the
here-document are not expanded. If word is unquoted, all
lines of the here-document are subjected to parameter
expansion, command substitution, and arithmetic expansion.
In the latter case, the character sequence \<newline> is
ignored, and \ must be used to quote the characters \, $,
and `.
If the redirection operator is <<-, then all leading tab
characters are stripped from input lines and the line
containing delimiter. This allows here-documents within
shell scripts to be indented in a natural fashion.
