How can the output of multiple functions be combined and returned as a single HTML output in PHP?

When we need to combine the output of multiple functions and return it as a single HTML output in PHP, we can use output buffering to capture the output of each function and then concatenate them together before returning the final HTML output. This allows us to organize and structure the different outputs into a single coherent HTML document. 

<?php
ob_start(); // Start output buffering

// Function 1
function function1() {
    echo "<h1>Hello</h1>";
}

// Function 2
function function2() {
    echo "<p>World!</p>";
}

// Capture output of function 1
function1();

// Capture output of function 2
function2();

$output = ob_get_clean(); // Get the buffered output and clean the buffer

// Return the combined HTML output
echo $output;
?>
