replacing specail chars in filenames

Hi,

How do I replace certain 'special' characters with a '_' in php ???

I need to replace @£!$%^^%&(*) etc as jpegs won't load in flash if they have any of these characters in there. If I convert them to unicode will that work ?? I could convert them to unicode after they're saved in the php file that outputs the XML file that flash parses, but I don't know if you can have unicode in filenames.

Any ideas ??

Thanks in advance,

Jon

I've just checked on the server and it's replacing any of these chars with a '_' itself, but the php is storing the filename in the DB with the @ so the filename is wrong, dam.

Hey, i suggest you use make a md5 hash of the filename.

in php i would look something like this:

$filename = "anyfile.jpg";
$md5filename = md5($filename);

if (!copy($filename, $md5filename)) {
die("failed to copy $filename...");
}

that way, you can parse the filename anywhere and if you need a random filename then replace $md5filename with this:

$md5filename = md5(uniqid(rand(),1));
(though i don't think it will be usefull in your case)


hope it helped you!
