What is the best way to count the number of characters in a string and potentially truncate it with ellipsis in PHP?

To count the number of characters in a string in PHP, you can use the `strlen()` function. If you want to truncate the string with an ellipsis (...) if it exceeds a certain length, you can use `substr()` to extract a portion of the string and concatenate it with the ellipsis. 

$string = "This is a long string that needs to be truncated";
$max_length = 20;

if(strlen($string) > $max_length){
    $string = substr($string, 0, $max_length) . '...';
}

echo $string;
