Footnote & Endnote

You can create footnotes with addFootnote and endnotes withaddEndnote in texts or textruns, but it's recommended to use textrun to have better layout. You can use addText, addLink,addTextBreak, addImage, addOLEObject on footnotes and endnotes.

On textrun:

<?php

$textrun = $section->addTextRun();
$textrun->addText('Lead text.');
$footnote = $textrun->addFootnote();
$footnote->addText('Footnote text can have ');
$footnote->addLink('http://test.com', 'links');
$footnote->addText('.');
$footnote->addTextBreak();
$footnote->addText('And text break.');
$textrun->addText('Trailing text.');
$endnote = $textrun->addEndnote();
$endnote->addText('Endnote put at the end');

On text:

<?php

$section->addText('Lead text.');
$footnote = $section->addFootnote();
$footnote->addText('Footnote text.');

By default the footnote reference number will be displayed with decimal number starting from 1. This number uses the FooterReference style which you can redefine with the addFontStyle method. Default value for this style is array('superScript' => true);

The footnote numbering can be controlled by setting the FootnoteProperties on the Section.

<?php

$fp = new \PhpOffice\PhpWord\ComplexType\FootnoteProperties();
//sets the position of the footnote (pageBottom (default), beneathText, sectEnd, docEnd)
$fp->setPos(\PhpOffice\PhpWord\ComplexType\FootnoteProperties::POSITION_BENEATH_TEXT);
//set the number format to use (decimal (default), upperRoman, upperLetter, ...)
$fp->setNumFmt(\PhpOffice\PhpWord\SimpleType\NumberFormat::LOWER_ROMAN);
//force starting at other than 1
$fp->setNumStart(2);
//when to restart counting (continuous (default), eachSect, eachPage)
$fp->setNumRestart(\PhpOffice\PhpWord\ComplexType\FootnoteProperties::RESTART_NUMBER_EACH_PAGE);
//And finaly, set it on the Section
$section->setFootnoteProperties($fp);
