You can use one of the following technique to remove the last comma(,)

Solution1:

$string = "'name', 'name2', 'name3',";  // this is the full string or text.
$string = chop($string,",");            // remove the last character (,) and store the updated value in $string variable.
echo $string;                           // to print update string.

Solution 2:

$string = '10,20,30,';              // this is the full string or text.
$string = rtrim($string,',');
echo $string;                       // to print update string.

Solution 3:

 $string = "'name', 'name2', 'name3',";  // this is the full string or text.
 $string = substr($string , 0, -1);
 echo $string;
