Hello everyone. I tried to find out wether a number is armstrong or not.My logic was right but few php errors are creeping.I am new to PHP.So please help me out. Here is the code armstrong.php <html> <head> <title> Armstrong number </title> </head> <body> <?php $arm=0; $i; $k; $i=$_POST["i"]; $j=$i; while($j!=0) { $k=$j%10; $arm=$arm+($k*$k*$k); $j=$j/10; } if($i==$arm) {echo "Yes it is an Armstrong number";} else {echo "No,it is not an Armstrong Number";} ?> <form method="POST" action="armstrong.php"> <input type="text" name="i" /> <br> <br> <input type="submit" name="submit" /> <input type="reset" name="reset" /> </form> </body> </html> The error is it shows "Yes it is an Armstrong number" by default when we open armstrong.php in browser.And when we enter a number and click submit,every thing goes fine. Here is a screenshot of it. <hr> And also some php errors are visible(undefined variable.....). Please help.
