Function Reference/trailingslashit

Appends a trailing slash.

Will remove trailing slash if it exists already before adding a trailing 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.

<?php trailingslashit( $string ) ?>

$string

(string) (required) What to add the trailing slash to.

Default: None

Since: 1.2.0
