How can debugging techniques help identify issues in PHP scripts?

Debugging techniques can help identify issues in PHP scripts by allowing developers to step through the code, track variable values, and identify where errors are occurring. By using tools like var_dump(), print_r(), and error_reporting(), developers can pinpoint the exact location of bugs and determine the root cause of issues. 

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

// Use var_dump() to print out variable values for debugging
$variable = "Hello";
var_dump($variable);

// Use print_r() to display the structure of arrays and objects
$array = array(1, 2, 3);
print_r($array);
?>
