PHP Program to print the numbers in reverse order.

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.

<?php

$number=123;
$orignal_num=$number;
$rs=0;
while($number>0)
{
$rs = $rs * 10 + $number % 10;
$number = (int)($number / 10);

}
print_r("Result:$orignal_num<br>Revrse of Number is= $rs");

PHP Program to print the numbers in reverse order with the form

In this example, we will take the inputs from the user and store them in variables.

<html>
<head>
<title></title>
   
</head>
<body>

                     <div class="nukr"><h2 class="col_insert" >Reverse Number</h2></div>
                     <form action="" method="post" name="insert_form" id="insert_form" class="comment-form">
                     <table class="tableI1" align="left" border="0" bordercolor="#FFFFFF" >
                     <tr><td ><b><i>Enter Number</b></i></td>
                     <td><input id="Charge" name="Charge" type="text" size="30" /> 
                     <tr><td></td><td><input type="submit" id="btnsubmit" name="btnsubmit" value="Calculate" size="30"/></td></tr>
                     <tr><td></td><td>       </td></tr>
                     </table>
                      </form>

</body>
</html>
<?php
if(isset($_POST['btnsubmit']))
{
$number=$_POST['Charge'];
$orignal_num=$number;
$rs=0;
while($number>0)
{
$rs = $rs * 10 + $number % 10;
$number = (int)($number / 10);

}
print_r("Result:$orignal_num<br>Revrse of Number is= $rs");
}

PHP Program to print the numbers in reverse order with the 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.

<html>
<head>
<title></title>
   
</head>
<?php
include 'dbconction.php';
?>
<body>

                     <div class="nukr"><h2 class="col_insert" >Reverse Number</h2></div>
                     <form action="" method="post" name="insert_form" id="insert_form" class="comment-form">
                     <table class="tableI1" align="left" border="0" bordercolor="#FFFFFF" >
                     <tr><td ><b><i>Enter Number</b></i></td>
                     <td><input id="Charge" name="Charge" type="text" size="30" /> 
                     <tr><td></td><td><input type="submit" id="btnsubmit" name="btnsubmit" value="Calculate" size="30"/></td></tr>
                     <tr><td></td><td>       </td></tr>
                     </table>
                      </form>

</body>
</html>
<?php
if(isset($_POST['btnsubmit']))
{
$number=$_POST['Charge'];
$orignal_num=$number;
$rs=0;
while($number>0)
{
$rs = $rs * 10 + $number % 10;
$number = (int)($number / 10);

}
$sql= "insert into reves(Number, Revers)
Value ('$orignal_num','$rs')";
   if($conn->query($sql)=== TRUE)
{
	echo"<font color=#FF00FF> New Record Inserted<br></font>";
	}
  else
  {
	  echo"Error:".$sql."<br>".$conn->error;
	  }	
print_r("Youer Input=$orignal_num<br>Revrse of Number is= $rs");
}

dbconnection.php

<?php

$username = "root";
$password = "";
$dbname = "fyp";
// Create connection
$conn = new mysqli($servername, $username, $password,$dbname);
