Are there any potential pitfalls to be aware of when splitting text into columns in PHP based on character count?

When splitting text into columns based on character count in PHP, one potential pitfall to be aware of is that the text may be split in the middle of a word, resulting in a fragmented output. To avoid this issue, you can use the `wordwrap()` function in PHP to wrap the text at a specified character count while keeping whole words intact. 

$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";
$columns = 20;

$wrapped_text = wordwrap($text, $columns, "\n", true);
$columns_array = explode("\n", $wrapped_text);

foreach ($columns_array as $column) {
    echo $column . "<br>";
}
