CakePHP Sum Array

Some project required developer to SUM the total value foreach variables in array. For example, if the table have column 'point' which stored the integer value such as 1, 3, 5 etc, the SUM value for the point array could be calculated by using these code:

Total Point: 
<?php $sum = 0;
	foreach ($users as $user)
		{
			$sum+= $user['User']['point'];	
		}
			echo $this->Number->precision($sum, 2);
?>

These code should be place at index where the value for each of the point will be display. The precision is '2' which it will produce result with 2 decimal point.

That all. Happy coding.
