Are there any recommended PHP libraries or resources that provide efficient solutions for handling string manipulation tasks like counting characters and truncating strings?

When handling string manipulation tasks like counting characters or truncating strings in PHP, it's recommended to use libraries or resources that provide efficient solutions to avoid reinventing the wheel. One popular library for string manipulation in PHP is the `mbstring` extension, which offers multibyte-specific string functions for working with Unicode characters. Additionally, the `str_word_count()` function can be used to count the number of words in a string, while `mb_substr()` can be used to truncate strings to a specified length.

// Counting characters in a string
$string = "Hello, World!";
$charCount = mb_strlen($string);
echo "Character count: " . $charCount;

// Truncating a string
$longString = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$truncatedString = mb_substr($longString, 0, 20) . "...";
echo "Truncated string: " . $truncatedString;
