How can a beginner in PHP improve their code efficiency and readability when working on complex tasks like generating calendars with multiple date ranges?

When working on complex tasks like generating calendars with multiple date ranges in PHP, beginners can improve their code efficiency and readability by breaking down the task into smaller, more manageable functions, using meaningful variable names, and commenting their code effectively. They can also utilize built-in PHP functions and libraries to streamline their code and reduce redundancy. 

<?php

// Function to generate a calendar for a specific month and year
function generateCalendar($month, $year) {
    // Your calendar generation logic here
}

// Function to calculate the number of days in a month
function getDaysInMonth($month, $year) {
    // Your logic to calculate days in a month here
}

// Function to check if a given date falls within a specific date range
function isDateInRange($date, $startDate, $endDate) {
    // Your logic to check date range here
}

// Main code to generate calendar with multiple date ranges
$startDate1 = '2022-01-01';
$endDate1 = '2022-01-15';

$startDate2 = '2022-02-01';
$endDate2 = '2022-02-28';

$month = 1;
$year = 2022;

generateCalendar($month, $year);

?>
