How can debugging techniques in PHP help identify and resolve errors in code efficiently?

Debugging techniques in PHP can help identify and resolve errors in code efficiently by allowing developers to track down issues in their code, such as syntax errors, logical errors, or runtime errors. Techniques like using var_dump() or print_r() to display variable values, using error reporting functions like error_reporting() and ini_set('display_errors', 1) to show error messages, and employing IDEs with built-in debugging tools can help pinpoint the source of the problem and fix it quickly. 

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

// Code snippet with debugging techniques
$number = 10;
$string = "Hello";

var_dump($number);
print_r($string);
?>
