Valid File Names

[ralphiooo]

Hi, i'm trying to do an image upload script. The problem i'm having is the file name part. Originally I created a random number but I realized it was a good idea to have the tile of the image within the name so I've decided to go for the title - some random numbers (to avoid duplicates). I was wondering if anyone knew what things I would have to strip/replace from a title to create a valid file name and what's the best way of doing it. Would appreciate any help. Thanks

the valid characters within a file name differ between unix and windows. do a google search to get the full charlists.

a code snip (i haven't run this code so sorry if there are parse errors within):

$bad_chars = array (";", ":", "/", "\\"); //for example
$filename = "" ; /some file name to test
$replacement_char = "_";
$safefilename = str_replace  
            ($bad_chars, 
             $replacement_char, 
             $filename, 
             $count);

echo "the new filename is $safefilename.  $count bad characters were replaced";
//note you may want to enquote the safefile name if it has spaces in it.
