How can PHP developers effectively debug their code when encountering errors or issues?

When encountering errors or issues in PHP code, developers can effectively debug by using tools like error reporting, logging, and debugging tools like Xdebug. They can also use techniques like var_dump(), print_r(), and die() to inspect variables and values during runtime. Additionally, breaking down the code into smaller parts and testing each part individually can help identify the root cause of the issue. 

// Example code snippet with error reporting and var_dump() for debugging
error_reporting(E_ALL);
ini_set('display_errors', 1);

$variable = "Hello, World!";
var_dump($variable);
