Hi Im trying do something like this, have a function which uploads my
file and returns file pointer ... but at same time ... I want to
remove all Blank lines in a file and update it before it goes to the
final location ...

What I tried was to do a write of file and use some regexp replace to
remove a blank ... either I am not doing the replace correct or my
understanding of the file buffer and what I can do with it between the
browser and saving is not correct,

Anyway my code looks something like this :

  $uploadfile     = $this->uploaddir;
             $mtran          = mt_rand(999,999999);
             $NewName        = date("Ymd_Gis").$mtran.".csv";
             $uploadfile     = $uploadfile.$NewName;

(move_uploaded_file($_FILES['attachfile']['tmp_name'], $uploadfile))
                     $handle = fopen($uploadfile, "r+");
                     $lines  = file($uploadfile,
                     foreach ($lines as $line_num =>  $line) {
                         $line =
preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "", $line);
                         if(strlen($line)>  0)
                             fwrite($handle, $line);

Suggest using file() which does must of the work for you. Then use foreach() to scan for empty lines. Recreate the array

Here is a quickie, not tested. Don't know what is the end of line on empties. So you need to adjust as needed.

$orgArray= file(path);
foreach($org as $line){
    if(empty($tl)) continue;
file_put_contents($filename, $newArray);
