Footnote creation snippet

[masonbarge]

I did a little footnote function today, if anybody can use one.

Code: Select all

<?php

$footnotes = array(0 => 'empty');

function footnote ($foottext){
    global $footnotes;
    global $foottext;
    array_push($footnotes, $foottext);
    end ($footnotes);
    $footnumber = key($footnotes);
    $ft = $foottext;
    echo "<a href=\"#fn$footnumber\"><span
 class=\"fn\">$footnumber</a></span>";
}

function footnote_print () {
    global $footnotes;
    echo '<div class="fns"><h4> Footnotes </h4>';
    reset ($footnotes);
    next ($footnotes);
    foreach ($footnotes as $k => $v) {
        if ($k >= 1) {
            echo "<a name=\"fn$k\">&nbsp;&nbsp; $k.&nbsp; $v</a><br />";
        }
    }
}

?>

Suggestions for improvement are welcome. It works like a dream except I haven't figured out how to style the text size or vertical-align of the footnote number yet.

To use it, type

Code: Select all

<p> I am examining my lovely belly button.';
<?php
$foottext = 'When the first man was born, he did not have a belly button. Booor-ing.';
footnote ($foottext);
?>
</p>

yada yada yada

--- and at the end of the text section, or wherever you want it ---

<? php
footnote_print();
?>
