# How to

## Create float left image

Use absolute positioning relative to margin horizontally and to line vertically.

``` php
<?php

$imageStyle = array(
    'width' => 40,
    'height' => 40,
    'wrappingStyle' => 'square',
    'positioning' => 'absolute',
    'posHorizontalRel' => 'margin',
    'posVerticalRel' => 'line',
);
$textrun->addImage('resources/_earth.jpg', $imageStyle);
```

## Download the produced file automatically

Use ``php://output`` as the filename.

``` php
<?php

$phpWord = new \PhpOffice\PhpWord\PhpWord();
$section = $phpWord->addSection();
$section->addText('Hello World!');
$file = 'HelloWorld.docx';
header("Content-Description: File Transfer");
header('Content-Disposition: attachment; filename="' . $file . '"');
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Expires: 0');
$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
$xmlWriter->save("php://output");
```

## Create numbered headings

Define a numbering style and title styles, and match the two styles (with ``pStyle`` and ``numStyle``) like below.

``` php
<?php

$phpWord->addNumberingStyle(
    'hNum',
    array('type' => 'multilevel', 'levels' => array(
        array('pStyle' => 'Heading1', 'format' => 'decimal', 'text' => '%1'),
        array('pStyle' => 'Heading2', 'format' => 'decimal', 'text' => '%1.%2'),
        array('pStyle' => 'Heading3', 'format' => 'decimal', 'text' => '%1.%2.%3'),
        )
    )
);
$phpWord->addTitleStyle(1, array('size' => 16), array('numStyle' => 'hNum', 'numLevel' => 0));
$phpWord->addTitleStyle(2, array('size' => 14), array('numStyle' => 'hNum', 'numLevel' => 1));
$phpWord->addTitleStyle(3, array('size' => 12), array('numStyle' => 'hNum', 'numLevel' => 2));

$section->addTitle('Heading 1', 1);
$section->addTitle('Heading 2', 2);
$section->addTitle('Heading 3', 3);
```

## Add a link within a title

Apply 'HeadingN' paragraph style to TextRun or Link. Sample code:

``` php
<?php

$phpWord = new \PhpOffice\PhpWord\PhpWord();
$phpWord->addTitleStyle(1, array('size' => 16, 'bold' => true));
$phpWord->addTitleStyle(2, array('size' => 14, 'bold' => true));
$phpWord->addFontStyle('Link', array('color' => '0000FF', 'underline' => 'single'));

$section = $phpWord->addSection();

// Textrun
$textrun = $section->addTextRun('Heading1');
$textrun->addText('The ');
$textrun->addLink('https://github.com/PHPOffice/PHPWord', 'PHPWord', 'Link');

// Link
$section->addLink('https://github.com/', 'GitHub', 'Link', 'Heading2');
```

## Remove [Compatibility Mode] text in the MS Word title bar

Use the ``Metadata\Compatibility\setOoxmlVersion(n)`` method with ``n`` is the version of Office:

* 14 = Office 2010
* 15 = Office 2013

``` php
<?php

$phpWord->getCompatibility()->setOoxmlVersion(15);
```
