What is the significance of using var_dump in PHP and how does it affect the output of values from Objects/Arrays?

When working with PHP, it is often necessary to debug and inspect the values of variables, especially when dealing with complex data structures like objects or arrays. The var_dump function is a useful tool for displaying the type and value of variables, making it easier to understand their structure and content. By using var_dump, developers can quickly identify any issues or inconsistencies in their code and make necessary adjustments. 

// Example of using var_dump to display the values of an object and an array

// Creating an example object
class ExampleObject {
    public $name = "John";
    public $age = 30;
}

$object = new ExampleObject();

// Creating an example array
$array = array("apple", "banana", "cherry");

// Using var_dump to display the values of the object and array
var_dump($object);
var_dump($array);
