[PHP]: Why "\" gives error while storing it in string?

Question

My string looks like:

$fullPath = $dirName . "/" . $file;

If I replace / with \, it gives error: "Expecting identifier or variable". I want to store in the latter way itself. How to override anything coming in between?

Answer 1

u need "\" cause \ is an escape character

interestingly : i cant put \ \ on SO as well .. so just remove the space "\ \"

Answer 2

\ is an escape character. Try \\ .

Answer 3

You need to escape the slash: $fullPath = $dirName . "\\" . $file;

Answer 4

Or wrap \ in single quotes, i.e. '\' since single quotes mean no escaping characters.
