I'm less drunk now, and once again this replacement seems wrong to me,
if you use a simple str_replace(array, array). Consider:
$a = "\\n";
$from = array("\\", "\n");
$to = array("\\\\", "\\n");
// forward conversion
$b = str_replace($from, $to, $a);
// backwards conversion
$c = str_replace($to, $from, $b);
$c will becomes "\n", not "\\n".
The reason, of course, is that str_replace does not respect escaped
characters. It is simpler to escape \ characters by appending a dummy
character than using a full fledged parser to perform a simple string-
replace.
