Are there any potential pitfalls to be aware of when using the explode function in PHP to separate strings?

One potential pitfall when using the explode function in PHP is that it may not handle empty values correctly, resulting in unexpected behavior or errors in your code. To solve this issue, you can use array_filter to remove any empty values from the resulting array after using explode.

$string = "apple,,banana,orange";
$delimiter = ",";
$parts = explode($delimiter, $string);
$parts = array_filter($parts);
