How can PHP developers improve code readability and maintainability to avoid errors like the ones discussed in the thread?

To improve code readability and maintainability in PHP, developers can follow best practices such as using meaningful variable names, breaking down complex code into smaller functions, commenting code effectively, and adhering to coding standards like PSR-12. By doing so, developers can reduce the likelihood of errors and make their code easier to understand and maintain. 

// Example of improved code readability and maintainability

    $total = 0;
    
    foreach ($items as $item) {
        $total += $item['price'];
    }
    
    return $total;
}
