How to Return Value From Function in PHP

PHP Return Value From Function

When PHP encounters a return statement inside a function, it halts the processing of the function and “returns” control to the main body of the program. Let’s see the example of return value from function in PHP


function cube($n){
return $n*$n*$n;

echo "Cube of 3 is : " . cube(3);

Cube of 3 is: 27

Factorial program return value

  function factorial($x)
   for($f=1, $i=1; $i<=$x; $i++)
      $f *= $i;
    return ($f);
echo "</br> Factorial of 5 = " . factorial(5);
echo "</br> Factorial of 7 = " . factorial(7);
