Numbers in a String in PHP
As you already know, strings can consist of digits. In this case, everything will work similarly:
<?php
$str = '12345';
echo $str[0]; // will output '1'
echo $str[1]; // will output '2'
echo $str[2]; // will output '3'
?>
You can, for example, find the sum of the first two digits of our number and it will work:
<?php
$str = '12345';
echo $str[0] + $str[1]; // will output 3
?>
Given a string '12345'. Find the sum
of the digits of this string.
