What are some potential pitfalls of using explode to split data in PHP, and how can they be avoided?

One potential pitfall of using explode to split data in PHP is that it does not handle cases where the delimiter may not exist in the input string, resulting in unexpected behavior or errors. To avoid this, you can use the isset() function to check if the array index exists before accessing it. 

$data = "apple,banana,orange";
$delimiter = ",";
$split_data = explode($delimiter, $data);

foreach ($split_data as $value) {
    if(isset($value)) {
        echo $value . "<br>";
    }
}
