How can code readability and consistency be improved in PHP scripts to avoid confusion and errors?

Code readability and consistency in PHP scripts can be improved by following coding standards, using meaningful variable names, properly indenting code, and commenting where necessary. This helps in making the code more understandable, maintainable, and less error-prone. 

// Example of improved code readability and consistency
<?php

// Define constants with meaningful names
define('MAX_ATTEMPTS', 3);
define('ERROR_MESSAGE', 'Invalid input. Please try again.');

// Use meaningful variable names
$username = $_POST['username'];
$password = $_POST['password'];

// Properly indent code
if ($username == 'admin' && $password == 'password') {
    echo 'Login successful';
} else {
    echo 'Login failed';
}
?>
