What are some common pitfalls when working with Closure objects in PHP?

One common pitfall when working with Closure objects in PHP is forgetting to bind variables from the parent scope using the `use` keyword. This can lead to unexpected behavior or errors when trying to access variables outside the Closure's scope. To solve this, make sure to explicitly bind any variables that need to be accessed within the Closure.

// Incorrect way - forgetting to bind variables from parent scope
$var = 10;
$closure = function() {
    echo $var; // This will cause an error
};
$closure();

// Correct way - binding variables from parent scope
$var = 10;
$closure = function() use ($var) {
    echo $var; // This will correctly output 10
};
$closure();
