How can PHP developers effectively manage and display NULL values in their applications?

When dealing with NULL values in PHP applications, developers can effectively manage and display them by using conditional statements to check for NULL values before attempting to display or manipulate them. This can help prevent errors and ensure a smooth user experience. Additionally, developers can use functions like is_null() or isset() to check for NULL values in variables before performing any operations on them. 

// Example code snippet to manage and display NULL values in PHP
$variable = NULL;

if(is_null($variable)){
    echo "Value is NULL";
} else {
    echo "Value is not NULL: " . $variable;
}
