How to use Arithmetic Operations In PHP
Take an integer with value 1. Then we will perform arithmetic operations on it to get an integer of only 1s which will be of same length as that or original integer. Then, finally we will add this integer to original integer to get the desired result.
Example: Illustration of incrementing by 1 to all the digits of a given integer in PHP using arithmetic operations.
PHP
<?php // Declaring the number$number = 1920;echo "Original Number: $number \n";// Number of digits in the number$len = strlen((string) $number);// Declaring another variable with value 1$add = 1;for ($i = 0; $i < $len; $i++) { // Adding variable $add and $number $number = $number + $add; // Multiplying the value of $add with 10 $add = $add * 10;}// Printing the resultecho "Incremented Number: $number";?> |
Output
Original Number: 1920 Incremented Number: 3031
How to Increment by 1 to all the Digits of a given Integer in PHP ?
In PHP, incrementing all digits of an integer by 1 involves breaking the number into individual digits, adding 1 to each, and reconstructing the integer. This can be accomplished through array manipulation, arithmetic operations, or string conversion methods. Suppose, if the given number is 123 then the desired output is 234.
Examples:
Input: 12345
Output: 23456
Input: 110102
Output: 221213
