The Fibonacci Sequence is the series of numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

  The next number is found by adding up the two numbers before it:

  • the 2 is found by adding the two numbers before it (1+1),
  • the 3 is found by adding the two numbers before it (1+2),
  • the 5 is (2+3),
  • and so on!
Now See The Full Php Script of Fibonacci Sequence.

echo " ";
   }
   //echo "<h5 style='text-align:center'>  Factorial Of " . $num1 ." = " . $fact . " </h5>";
