i have a php file named test.php, the last line number is 30, and it is an empty line
\pcov\collect() return an array

array(1) {
  ["/webroot/localhost/pcov/src/test.php"] => array(10) {
    [30] => int(-1)
    [11] => int(1)
    [12] => int(-1)
    [13] => int(1)
    [14] => int(1)
    [17] => int(1)
    [18] => int(1)
    [19] => int(1)
    [22] => int(1)
    [26] => int(-1)
  }
}

why the key of first item in the return array is 30.

Hard to tell, if you can't show that file.
