Description: This simple script takes user files from a form and uploads them to an FTP site with a friendly name. Uses the PHP FTP functions. Also has some error checking.
<?
//uses $_FILES[] global array
//see manual for older PHP version info
//This function will be used to get the extension from the filename

$p = strrpos($file,".");

if($length!=-1){
$ext = substr($file,$p,$length);
}
if($length==-1){
$ext = substr($file,$p);
}
$ext = strtolower($ext);
return $ext;
