How can debugging techniques like var_dump() help identify issues with PHP classes and functions?

Debugging techniques like var_dump() can help identify issues with PHP classes and functions by allowing developers to inspect the values of variables at different points in their code. By using var_dump(), developers can print out the contents of variables, arrays, and objects to see if they contain the expected data. This can help pinpoint where the issue lies and what values are causing the problem. 

class MyClass {
    public function myFunction($param) {
        var_dump($param); // Use var_dump() to inspect the value of $param
        // Rest of the function code
    }
}

$obj = new MyClass();
$obj->myFunction("Hello World");
