Percentage of a number from another number

Question

How to find the percentage of a number of another number in PHP?

Example

$num1 = 2.6; $num2 = 2.6; // Should equal to 100% 

Answer 1

Divide the two numbers and multiply them by 100 to get a percentage:

 $percentage = ($num1 / $num2) * 100; echo $percentage . "%"; 

Of course, you will need to check that $num1 not 0, something like this: $percentage = ($num1 !== 0 ? ($num1 / $num2) : 0) * 100;

Answer 2

 $percentage = sprintf("%d%%", $num1 / $num2 * 100); // string: 100%
