What is the best way to limit the length of a string in PHP without cutting off words?

When limiting the length of a string in PHP, it's important to avoid cutting off words in the middle. One way to achieve this is by using the `wordwrap()` function, which wraps a string to a given number of characters without breaking words. By specifying the desired length and a line break character, we can limit the length of the string without cutting off words.

$string = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$limitedString = wordwrap($string, 20, "\n", true);

echo $limitedString;
