By using preg_replace you can strip the 'PHP' part and the comma from value.

echo preg_replace('|  PHP (\d+),(\d+)|', '$1$2', $array[5]) + preg_replace('|  PHP (\d+),(\d+)|', '$1$2', $array[11]);

or if the number of spaces is random '\s' is any whitespace char

    echo preg_replace('|\s+PHP\s+(\d+),(\d+)|', '$1$2', $array[5]) + preg_replace('|\s+PHP\s+(\d+),(\d+)|', '$1$2', $array[11]);

or str_replace()
