Small preg_match Help

Hello,

I have this script where it checks the name of a folder, and only allows if it is in format of "something" or "blah blah"

preg_match ( '#[^a-z0-9_\s]|\s{2,}#i', $folder_name )

Code (markup):

Can anyone help me turn that into something which only allows folder with a "-" instead of space ? or which replaces space with a "-"

I tried looking through http://www.php.net/preg_match but got stuck...

Thanks

 

In your pattern, replace \s (both) with the dash.

 

Thanks a lot

Is there any quick way to automatically replace space with dash ?

 

$folder_name = str_replace(' ', '-', $folder_name);

PHP:

 

Wonderful,

Many thanks again
