Php - allow spaces in rewriteRule

Question

i have this current url rewrite:

RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?id=$1

Now i need to add, that every space is replaced with a "-", but how can i add this to my rewrite? is this possible doing it this way?

Answer 1

You can accept spaces in your rewrite rule:

RewriteRule ^([(a-zA-Z0-9_-]|\s)+)$ index.php?id=$1

Then in index.php you would have to replace the spaces with underscores:

preg_replace('/\s+/', '_', $id);
