Are there any best practices for handling complex string manipulation tasks in PHP, especially for beginners?

When handling complex string manipulation tasks in PHP, especially for beginners, it's important to break down the task into smaller, manageable steps. Utilize built-in PHP string functions such as `str_replace`, `substr`, `explode`, and `implode` to manipulate strings effectively. Regular expressions can also be powerful tools for more advanced string manipulation tasks.

// Example of using str_replace to manipulate a string
$string = "Hello, World!";
$newString = str_replace("Hello", "Hi", $string);
echo $newString;
