A simple PHP reading CSV file method

1. The idea: to open a file, read the file number of the line, then read line by line data into an array

public function read_csv_lines($csv_file = '', $lines = 0, $offset = 0)
{
     if (!$fp = fopen($csv_file, 'r')) {
         return false;
     }

     $i = $j = 0;

     while (false !== ($line = fgets($fp))) {
         if ($i++ < $offset) {
             continue;
         }
         break;
     }

     $data = array();

     while (($j++ < $lines) && !feof($fp)) {
         $data[] = fgetcsv($fp);
     }

     fclose($fp);
     return $data;
 }
