Laravel - CSV - getting only one row as response

I have one CSV file with two fields field1 and field2. When I try to loop throught each row of my CSV file it only return first row of file.

Notice, that file is uploaded and valid.

Here is my code:

/**
 * Get File Contents
 */
 $csv = Reader::createFromPath(storage_path('folder/'.$FILE_NAME));
 $csv->setOffset(1);

/**
 * CSV Properties
 */
 $delimiter = $csv->getDelimiter();
 $enclosure = $csv->getEnclosure();

 /**
  * Processing CSV File
  */
 $temp_data = "";
 $csv->each(function($row) use ($position1, $position2, $delimiter, &$temp_data, $enclosure)
 {
    $temp_data .= $enclosure.$row[$position1].$enclosure.$delimiter.
                    $enclosure.$row[$position2].$enclosure."/n";

    echo $temp_data;
 });

 exit;

Does anyone have an idea why I'm getting only the first row of the file?
