What potential issue can arise when using chunk_split() in PHP and how can it be addressed?

When using chunk_split() in PHP, one potential issue that can arise is that the function can add extra characters to the end of the string, such as a newline character. This can cause unexpected behavior if the extra characters are not accounted for. To address this issue, you can use rtrim() to remove any unwanted characters from the end of the chunked string. 

$originalString = "Lorem ipsum dolor sit amet";
$chunkedString = chunk_split($originalString, 5, "-");
$cleanedString = rtrim($chunkedString, "-");

echo $cleanedString;
