How can one effectively troubleshoot and debug a buggy PHP website?

To effectively troubleshoot and debug a buggy PHP website, one can start by checking for syntax errors, ensuring error reporting is turned on, and using tools like Xdebug for more advanced debugging. It's also helpful to break down the code into smaller parts to isolate the issue and use print statements or var_dump to inspect variables and outputs.

// Example code snippet demonstrating the use of var_dump for debugging
$variable = "Hello World";
var_dump($variable);
