## Working with the OO API

This example shows how to work with XMLWriter's object-oriented API.

Example #1 Working with the OO API

`<?php
$xw = new XMLWriter();
$xw->openMemory();
$xw->startDocument("1.0");
$xw->startElement("book");
$xw->text("example");
$xw->endElement();
$xw->endDocument();
echo $xw->outputMemory();`

The above example will output:

    <?xml version="1.0"?>
    <book>example</book>

`↑` and `↓` to navigate • `Enter` to select • `Esc` to close • `/` to open
