How can PHP developers ensure the correct order of output when using multiple functions for HTML generation?

When using multiple functions for HTML generation in PHP, developers can ensure the correct order of output by using output buffering. By capturing the output of each function in a buffer and then echoing the contents in the desired order, developers can prevent any unexpected rearrangement of HTML elements. 

<?php
ob_start();

function generateHeader() {
    echo "<header>This is the header</header>";
}

function generateContent() {
    echo "<div>This is the content</div>";
}

function generateFooter() {
    echo "<footer>This is the footer</footer>";
}

generateHeader();
generateContent();
generateFooter();

ob_end_flush();
?>
