What are the potential pitfalls of using explode and implode functions in PHP?

One potential pitfall of using explode and implode functions in PHP is that they can be inefficient when dealing with large strings or arrays. To solve this issue, consider using alternative methods like preg_split or join for better performance. 

// Using preg_split instead of explode for better performance
$string = "apple,banana,orange";
$array = preg_split("/,/", $string);

// Using join instead of implode for better performance
$newString = join(",", $array);
