How can var_dump be a useful tool for debugging in PHP, and what are its limitations?

Var_dump is a useful tool for debugging in PHP as it allows you to inspect the type and value of variables at any point in your code. This can help you identify issues such as unexpected variable types or values. However, var_dump can be overwhelming when used on complex data structures, and it can clutter the output with a lot of information.

// Using var_dump to debug a variable
$variable = "Hello, World!";
var_dump($variable);
