What alternative PHP functions can be used for accurate character length calculations in multibyte strings?

When dealing with multibyte strings in PHP, it's important to use functions that are multibyte-safe for accurate character length calculations. One common issue is using functions like `strlen()` which count bytes instead of characters in multibyte strings. To accurately calculate the character length of multibyte strings, you can use functions like `mb_strlen()` which are specifically designed to handle multibyte characters. 

// Using mb_strlen() to accurately calculate character length in multibyte strings
$multibyteString = "こんにちは"; // Japanese greeting "Konnichiwa"
$characterLength = mb_strlen($multibyteString, 'UTF-8');
echo "Character length of the multibyte string is: " . $characterLength;
