What potential pitfalls can arise when trying to shuffle a string instead of an array in PHP?

When trying to shuffle a string instead of an array in PHP, a potential pitfall is that the string will be treated as an array of characters, resulting in the characters being shuffled instead of the entire string. To solve this issue, you can convert the string into an array of characters, shuffle the array, and then implode the array back into a string. 

$string = "Hello World";
$chars = str_split($string); // Convert string to array of characters
shuffle($chars); // Shuffle the array
$shuffledString = implode('', $chars); // Implode the array back into a string
echo $shuffledString;
