Replacing any instances of a single character

[timd]

Ok, this is driving me nuts! I've got two problems at the moment:

I've got a whole load of requests coming in with the format:

Code: Select all

www.foo.bar/this_is_the_page.php

but the filenames are actually in the format

Code: Select all

www.foo.bar/this-is-the-page.php

So first question is how on earth I replace any and all instances of '_' with '-'

The second question is whether it's possible to trim the inbound

Code: Select all

this_is_the_page

ie everything between the last / and the first . to a maximum of 25 characters?

I'm sure they've both got to be really simple questions if you're in the know, but they're driving me nuts!

No, this is a more complex issure, because your webserver might crash (runs out of virtual memory) due to looping sub-requests under some circumstances.

see viewtopic.php?p=1618#1618

Code: Select all

RewriteEngine On
RewriteRule ^(.+)_(.+)\.php$ $1-$2.php [N]
RewriteRule ^(.*)-(.*)\.php$ $1-$2.php [R=301,L]

ie everything between the last / and the first . to a maximum of 25 characters?

There is no slash for http//www.foo.bar/this-is-the-page.php. mod_rewrite in a .htaccess in http//www.foo.bar/.htaccess will only see the red part of the URL
