How to check the given number is either Palindrome number or not in PHP?<\/p>\n\n\n\n

What is the Palindrome number?<\/p>\n\n\n\n

A palindrome is a word , number, phrase, verse or sentence that reads the same forward and backward.<\/p>\n\n\n\n

Here , we’ll see the palindrome number:<\/p>\n\n\n\n

Logic<\/strong>: Its logic has same like reverse number, in further we’ll check the given number and reverse number is equal or not.<\/p>\n\n\n\n

  1. First of all, the remainder of $num<\/var> divided by 10 is stored in the variable $rem. Now, $rem contains the last digit of $num, i.e. 1.<\/li>
  2. $rem is then added to the variable $rev after multiplying it by 10.<\/li>
  3. Multiplication by 10 adds a new place in the $rev contains. $rev contain like this 0 * 10 + 1 = 1.<\/li>
  4. $num is then divided by 10 so that now it only contains first four digits: 1232.<\/li>
  5. After second iteration, $rem equals 2, $rev<\/var> equals 1 * 10 + 2 = 12 and $num<\/var> = 123.<\/li>
  6. After third iteration, $rem equals 3, $rev<\/var> equals 12 * 10 + 3 = 123 and $num<\/var> = 12.<\/li>
  7. After fourth iteration, $rem equals 2, $rev<\/var> equals 123 * 10 + 2 = 1232 and $num<\/var> = 1.<\/li>
  8. After fifth iteration, $rem equals 1, $rev<\/var> equals 1232 * 10 + 1 = 12321 and $num<\/var> = 0.<\/li>
  9. Now, $num will be existed outside the while loop and $rev contains 12321.<\/li><\/ol>\n\n\n\n

    Now , look at this coding<\/p>\n\n\n\n
