    You could roll your own. function twoColorCircle($a, $b, $sz) { $out = "<svg width='$sz' height='$sz' viewBox='0 0 1000 1000'> <linearGradient id='grad2' x1='0' y1='0' x2='1' y2='0'> <stop offset='0%' style='stop-color:$a'/> <stop offset='50%' style='stop-color:$a'/> <stop offset='50%' style='stop-color:$b'/> <stop offset='100%' style='stop-color:$b'/> </linearGradient> "; $c = 500; $r = 499; $out .= "<circle cx='$c' cy='$c' r='$r' fill='url(#grad2)' stroke='#000' /> </svg>"; return $out; } foreach ([16,32,64,128,256] as $sz) echo twoColorCircle('#5fc75d' , '#f19e2d' , $sz); echo '<br>'; foreach (['16em','8em','4em','2em','1em'] as $sz) echo twoColorCircle('#5fc75d' , '#f19e2d' , $sz);

    Alternatively, define your monetary amount columns as decimal(). This gives fixed number of decimal places. Here's an example DATA CREATE TABLE `income` ( CREATE TABLE `expense` ( `income_id` int(11) NOT NULL AUTO_INCREMENT, `expense_id` int(11) NOT NULL AUTO_INCREMENT, `userid` int(11) DEFAULT NULL, `userid` int(11) DEFAULT NULL, `pay_date` date DEFAULT NULL, `expend_date` date DEFAULT NULL, `amount` decimal(10,2) DEFAULT NULL, `expamount` decimal(10,2) DEFAULT NULL, PRIMARY KEY (`income_id`), PRIMARY KEY (`expense_id`), KEY `idx_income_userid` (`userid`) KEY `idx_expense_userid` (`userid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; ) ENGINE=InnoDB DEFAULT CHARSET=utf8; income expense +-----------+--------+------------+---------+ +------------+--------+-------------+-----------+ | income_id | userid | pay_date | amount | | expense_id | userid | expend_date | expamount | +-----------+--------+------------+---------+ +------------+--------+-------------+-----------+ | 1 | 1 | 2020-01-01 | 2500.00 | | 1 | 1 | 2020-01-15 | 800.00 | | 2 | 1 | 2020-02-01 | 2650.00 | | 2 | 1 | 2020-01-25 | 250.00 | | 3 | 1 | 2020-03-01 | 2400.00 | | 3 | 2 | 2020-01-21 | 1500.00 | | 4 | 2 | 2020-01-01 | 3000.00 | | 4 | 2 | 2020-02-10 | 500.00 | | 5 | 2 | 2020-02-01 | 3100.00 | | 5 | 2 | 2020-03-15 | 1800.00 | | 6 | 2 | 2020-03-01 | 2800.00 | | 6 | 2 | 2020-03-20 | 1600.00 | +-----------+--------+------------+---------+ +------------+--------+-------------+-----------+ QUERY SELECT i.userid , mname , income , expense , income - expense as diff FROM ( SELECT userid , EXTRACT(YEAR_MONTH from pay_date) as month , MONTHNAME(pay_date) as mname , SUM(amount) as income FROM income GROUP BY userid, month ) i LEFT JOIN ( SELECT userid , EXTRACT(YEAR_MONTH from expend_date) as month , SUM(expamount) as expense FROM expense GROUP BY userid, month ) e USING (userid, month); +--------+----------+---------+---------+---------+ | userid | mname | income | expense | diff | +--------+----------+---------+---------+---------+ | 1 | January | 2500.00 | 1050.00 | 1450.00 | | 1 | February | 2650.00 | NULL | NULL | | 1 | March | 2400.00 | NULL | NULL | | 2 | January | 3000.00 | 1500.00 | 1500.00 | | 2 | February | 3100.00 | 500.00 | 2600.00 | | 2 | March | 2800.00 | 3400.00 | -600.00 | +--------+----------+---------+---------+---------+

    Use $diff->days. $dt1 = new DateTime('2020-05-01'); $diff = $dt1->diff(new DateTime())->d; //--> 14; $diff = $dt1->diff(new DateTime())->days; //--> 44; ->d gives the days as in "1 month 14 days" ->days gives the total days Using SQL: select datediff(curdate(), '2020-05-01') as days; +------+ | days | +------+ | 44 | +------+
