`Correction to previous post: ob_get_clean() is better, ie:
<?php
// start generating html
$html = '<html><head>'; // etc
// start output buffering
ob_start();
// call function which outputs immediately
print_menu();
// append this to $html and empty buffer
$html .= ob_get_clean();
?>`

`I found this function is useful for storing output instead of displaying it. For example, I wanted to use an old function which echoed the ouput but I wanted it in a variable, not outputted immediately. Here's how:
<?php
// start generating html
$html = '<html><head>'; // etc
// start output buffering
ob_start();
// call function which outputs immediately
print_menu();
// append this to $html
$html .= ob_get_flush();
// empty output buffer
ob_clean();
?>`
