Skip first line of fgetcsv method

try:

$flag = true;
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE) {
   if($flag) { $flag = false; continue; }
   // rest of your code
}

Before beginning the while loop, just get the first line and do nothing with it. This way the logic to test if it's the first line is not needed.

fgetcsv($file, 10000, ",");
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE) {
  //....
}
