PHP program to find the factorial of a number.
In this example, programmer stores the values in the variables. However, if you interested to see the program about taking values in the form, please see example 2.
<html>
<body>
<?php
$p = 3;
$f = 1;
for ($x=$p; $x>=1; $x--)
{
$f = $f * $x;
}
echo "Factorial of number is $f";
?>
</body>

PHP program to find the factorial of a number with form.
In this example, we will take the inputs from the user and store them in variables.
<html>
<body>
<form method="post">
<input type="text" name="name"/>
<input type="submit" name="OK" />

if(isset($_POST['OK'])){
$p =$_POST['name'];
$f = 1;
for ($x=1; $x<=$p; $x++)
{
$f = $f * $x;
}
echo "Factorial of number is $f ";
}
?>
</body>

PHP program to find the factorial of a number with a database.
In this example, we will take the inputs from the user and temporarily store them in variables and then finally stores them permanently in the database.

if(isset($_POST['OK'])){
$p =$_POST['name'];
$f = 1;
for ($x=1; $x<=$p; $x++)
{
$f = $f * $x;
}
echo "Factorial of number is $f ";
$sql=mysqli_query($con,"INSERT INTO Factorial (Number,Factorial) VALUES ('$p','$f')");
}
?>
</body>
