How can errors in PHP scripts be effectively debugged and resolved?

To effectively debug and resolve errors in PHP scripts, you can use tools like error reporting, logging, and debugging tools like Xdebug. Additionally, you can enable display_errors in your PHP configuration to see errors directly on the page. Using try-catch blocks and var_dump() or print_r() functions can help you identify and fix errors in your code. 

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

// Example code with error
$number = 10;
$divisor = 0;
$result = $number / $divisor;

// Using try-catch block to handle the error
try {
    $result = $number / $divisor;
    echo $result;
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}

// Using var_dump() to debug
var_dump($result);
