What are the best practices for writing code to calculate the length of meta descriptions in PHP?

When calculating the length of meta descriptions in PHP, it's important to consider the maximum character limit allowed by search engines like Google (typically around 160 characters). To ensure that your meta descriptions are within this limit, you can use the mb_strlen() function in PHP to accurately count the number of characters in the description. 

$meta_description = "Your meta description here";
$description_length = mb_strlen($meta_description);

if($description_length > 160){
    // Handle error or truncate the description
}
