How can var_dump() be effectively used to debug PHP code and identify issues with variables?

To effectively use var_dump() to debug PHP code and identify issues with variables, you can simply insert var_dump() statements at key points in your code to output the values of variables. This can help you see the actual data stored in variables and identify any unexpected values or types. Additionally, you can use var_dump() in combination with die() or exit() to halt the script execution at a specific point and inspect the variable values. 

// Example of using var_dump() to debug PHP code
$variable1 = 'Hello';
$variable2 = 123;

var_dump($variable1);
var_dump($variable2);

// Use var_dump() with die() to halt script execution and inspect variable values
var_dump($variable1); 
die();
