What are the drawbacks of using preg_split() as a solution for formatting database field data into lists in PHP?

Using preg_split() to format database field data into lists in PHP may not be the most efficient solution as it relies on regular expressions which can be slower compared to other methods. Additionally, preg_split() may not handle all edge cases or variations in the data format, leading to unexpected results. A more robust approach would be to use PHP's explode() function, which is simpler and faster for splitting strings based on a delimiter. 

// Example code using explode() to format database field data into lists
$data = "apple,banana,orange";
$list = explode(",", $data);

foreach ($list as $item) {
    echo $item . "<br>";
}
