You may try this 

  <?php     

      $name = 'Firstname,';   // If you give value "," you will get blank

      $filename_withou_comma = explode (',',$name);
      echo $filename_withou_comma[0];
      echo $filename_withou_comma[1];

      ?>

You can replace all occurrences of a string from within a string with str_replace, which will work even if the comma is in the middle of the string.

//Here we are replacing all occurrences of "," with "" inside $string
$string = str_replace(",", "", $string);

If you just want to remove the commas from the left / right, then trim() is the way to go, as follows:

$string = trim($string, ",");

Hope I was helpful!

If your comma is only at the beginning and at the end of your string you could do that: 

$firstname = rtrim('firstname', ',');
$lastname = ltrim(', lastname', ', ');

Check out ltrim and rtrim
