What does the deprecation warning "php ucwords(): Passing null to parameter #1 ($string) of type string is deprecated" indicate in PHP 8.2?

The deprecation warning indicates that passing a null value to the ucwords() function in PHP 8.2 is deprecated. To solve this issue, you should ensure that the parameter passed to ucwords() is a valid string and not null. You can check for null values before calling ucwords() to avoid triggering the deprecation warning. 

$string = null;

if ($string !== null) {
    $result = ucwords($string);
    echo $result;
} else {
    echo "String is null.";
}
