PHP program to check for a Palindrome number

 

A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16461) that remains the same when its digits are reversed. In other words, it has reflectional symmetry across a vertical axis.

code:-

<?php

$num = 131;  

$x = 0;

$n =$num;

 

while(floor($num))

{  

$mod = $num%10;

$x = $x * 10 + $mod;  

$num = $num/10;

}  

 

if($n==$x)

{  

echo "$n is a Palindrome number.";  

}

 

else

{  

echo "$n is not a Palindrome number.";  

}  

?> 

output:-

131 is not a Palindrome number.
