How to remove first slash after URL?

Question

htaccess

Good time of the day.
I am using PHP routing.
htaccess:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?route=$1 [B,L,QSA]
And I can't get rid of double (triple, etc.) e.) slash right after the site address.
For example site.ru/article////page/5 in GET['route'] we get article////page/5 and the router will redirect to site.ru/article/page/5
But site.ru// //article/page/5 It won't redirect anywhere, since the GET['route'] parameter will contain article/page/5 and, accordingly, there will be no redirection.
No one will help with advice.

Answer 1

RewriteCond %{THE_REQUEST} //
RewriteRule ^(.*)$ /$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?route=$1 [B,L,QSA]

Answer 2

If the user himself drives a URL with all sorts of garbage into the address bar, then he needs to wring his hands to give an error 404

Answer 3

you can do a check in index.php for example - use the trim functions (many different videos about this)
