preg replace problem

[Smudly]

Hi, I am having a pretty difficult time getting files to upload to my server that have a Single Quote in the file name.

Example:

 

myfile's.pdf

 

I need to strip the file name of the quote before it uploads to the server.

I currently am using SWFUpload and this is the bit of code that was included with it.

 

I need to modify it to remove the single quotes as well. Been hammering my head over this all day.

 

$file_name = preg_replace('/[^'.$valid_chars_regex.']|\.+$/i', "", basename($_FILES[$upload_name]['name']));
if (strlen($file_name) == 0 || strlen($file_name) > $MAX_FILENAME_LENGTH) {
	HandleError("Invalid file name");
	exit(0);
}

 

thanks
