In what situations would using the "use" keyword in anonymous functions be beneficial in PHP?

Using the "use" keyword in anonymous functions in PHP is beneficial when you need to access variables from the parent scope within the anonymous function. This is particularly useful when you want to pass variables from outside the function into the function without explicitly passing them as parameters. 

// Example of using the "use" keyword in an anonymous function
$outerVariable = 10;

$anonymousFunction = function() use ($outerVariable) {
    return $outerVariable * 2;
};

echo $anonymousFunction(); // Output: 20
