Get Percentage Of A Number With PHP

Use the following function to find the percentage value of one number to another. If the $total parameter is zero then zero is returned as this would otherwise result in a division by zero error.

function get_percentage($total, $number)


{


  if ( $total > 0 ) {


   return round($number / ($total / 100),2);


  } else {


    return 0;


  }


}

Here are some examples of the function in action.

echo get_percentage(100,50).'%'; // 50%


echo get_percentage(100,10).'%'; // 10%


echo get_percentage(100,100).'%'; // 100%


echo get_percentage(400,3).'%'; // 0.75%


echo get_percentage(1234,4321).'%'; // 350.16%
