Description:
------------
$handle = open('test.csv','r+');
fputcsv($handle,$content);

If i write this, the last line is not overwritten:

$handle = open('test.csv','r+');
while($current = fgetcsv(handle)) {
    //Nothing
}
fputcsv($handle,$content);

$handle = open('test.csv','r+');
fputcsv($handle,$content);
//Work
$handle = open('test.csv','r+');
