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 
function get_extension($file,$length=-1){ 
$p = strrpos($file,"."); 
$p++; 
if($length!=-1){ 
  $ext = substr($file,$p,$length); 
} 
if($length==-1){ 
  $ext = substr($file,$p); 
} 
$ext = strtolower($ext); 
return $ext; 
} 

//Not good practice, but here anyway 
//change to suit your needs 

//2meg max 
ini_set("upload_max_filesize","2M"); 

//turn on file uploads 
ini_set("file_uploads","1"); 

//set your temp dir 
ini_set("upload_tmp_dir","/tmp"); 

//set post size large enough to accomidate 
//3 2meg files and some overhead 
ini_set("post_max_size","8M");
