How can debugging techniques be used effectively in PHP to identify errors in code?

To effectively use debugging techniques in PHP to identify errors in code, you can start by using tools like var_dump() or print_r() to output the values of variables at different points in your code. Additionally, enabling error reporting and logging can help pinpoint where issues are occurring. Using an IDE with built-in debugging tools can also be beneficial in stepping through code and identifying errors. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Output variable values for debugging
var_dump($variable);
print_r($array);

// Use a debugger in an IDE to step through code
