Calculating the Hypotenuse in PHP

Another way of calculating this is to use the Hypot () function. They Hypot function is written as hypot (num, num); with the first number being one side of the triangle (a) and the second number being the other side (b). It will output the hypotenuse. Here is an example of how to use it.

 <?php 
 $a = 3;
 $b = 4;
 $c = hypot ($a, $b);
 echo "a = " .$a. "<br>";
 echo "b = " .$b. "<br>";
 echo "c = " .$c. "<br>";
 ?> 

Again, with this script you can replace a and b with any values and it will calculate c.
