What is forward slash in PHP?

Forward Slash: / A good way to remember the difference between a backslash and a forward slash is that a backslash leans backwards ( / ), while a forward slash leans forward ( / ). In Windows backslashes are used to separate directories in file paths (ex:C:/Program Files/Common Files/microsoft shared).

You can sometimes use a single backslash, but sometimes you need two. When you can use a single backslash depends on two things: the character immediately following the backslash. If you have a double quote string the backslash is treated as an escape character in many cases so it is best to always escape the backslash with another backslash:
