compute and print sum of two given integers (more than or equal to zero). if given integers or the sum have more than 80 digits, print "overflow" in PHP


🤖 Code Explanation

In the code above, $a and $b are assigned string values. The $c variable is assigned the value of $a + $b, which results in the concatenation of the two strings. If the length of $c is greater than 80, the code will output "overflow". Otherwise, it will echo the value of $c.
