A simple technical question that may be given is how can you determine if a word is a palindrome or not? A palindrome is a word that can be spelled forward and backwards the same way.
Some example palindromes are:
- madam
- anna
- civic
- kayak
- level
- racecar
- noon
- mom
- dad
A way to solve this in PHP is to take your string, split it into an array, reverse the contents of the array, and turn it back into a string. An even simpler way is to use the ‘strrev’ function, but that takes away all the fun now doesn’t it?
