How to escape '\' from a string in PHP?

Question

I am using File IO, to save a file in local system(i.e PC C: drive), URL to save is like this "C:\htmlfiles\".$name_of_file.".html" the "\" in the string "C:\htmlfiles\" is giving the problem, tell me how to escape the '\'. please help.

Answer 1

\ is escaped by \ (like all the other special chars, too), so the result would be \\

Answer 2

For the pathnames you can use forward slash on Windows too
"C:/htmlfiles/" would work
