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