How can debugging tools like var_dump be utilized to identify and resolve issues with PHP code?

To identify and resolve issues with PHP code using debugging tools like var_dump, you can use var_dump to display the contents of variables at specific points in your code to understand their values and data types. This can help you pinpoint where issues may be occurring, such as incorrect variable values or unexpected data types. By using var_dump strategically throughout your code, you can track the flow of data and identify the source of any bugs or errors.

// Example code snippet utilizing var_dump for debugging

var_dump($variable1);
var_dump($variable2);
var_dump($variable3);
