trailingslashit( string $string )

Appends a trailing slash.


Description

Will remove trailing forward and backslashes if it exists already before adding a trailing forward slash. This prevents double slashing a string or path.

The primary use of this is for paths and thus should be used for paths. It is not restricted to paths and offers no specific path support.
