If you only want https://kingphp.com/money directory become https://kingphp.com, use:
RewriteRule ^catalog/$ / [L]
If you want all directories become https://kingphp.com, use:
RewriteRule ^([^/]+)$ /catalog/$1 [L]
RewriteRule ^$ /catalog/ [L]
Note:If you have other subfolders in there (in that catalog dir, you’ll need some additional rule for that also. This will rewrite your files from catalog/ subfolder to your main url.
