How can error reporting and debugging techniques be utilized effectively to identify and resolve PHP script errors that prevent proper display of web pages?

To effectively identify and resolve PHP script errors that prevent proper display of web pages, error reporting can be enabled by setting error_reporting to E_ALL and display_errors to 1 in the php.ini file. Additionally, debugging techniques such as using var_dump() or print_r() to inspect variables and functions can help pinpoint the source of errors. By carefully examining error messages and utilizing debugging tools, developers can quickly identify and fix PHP script errors.

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

// Debugging technique - var_dump() to inspect variables
$variable = 5;
var_dump($variable);

// Debugging technique - print_r() to inspect arrays
$array = array(1, 2, 3);
print_r($array);
