Hi,
I actually had that ... removed it in last example as I was trying other
stuff and it did not seem to work either ?
$lines = file($uploadfile, FILE_SKIP_EMPTY_LINES); //FILE_IGNORE_NEW_LINES
|
see I removed the FILE_IGNORE line - it was in earlier and only tried
FILE_SKIP_EMPTY .... but still the final file had all the spaces again ...
So in the file it would look like (from the original file the user uploads
that is)
1
2
3
4
5
6
but when the file is saved to the server it must look like
1
2
3
4
5
6
but it never does and still looks like the first block.
