I combined HTML with PHP to generate a web page. My PHP code is: 

public function generateSelect()
{
    $data = "<select>\n";

    for ($i = 2000;$i<=2012;$i++)
    {
        $data .= "\t<option value='$i'>$i</option>\n";
    }
    $data .= "</select>";
    $this->data = $data;
    return $this;
}

And this is my HTML: 

<div>
    <?= $data ?>
</div>

And this is the result: 

<div>
    <select>
    <option value='2000'>2000</option>
    <option value='2001'>2001</option>
    <option value='2002'>2002</option>
    <option value='2003'>2003</option>
    <option value='2004'>2004</option>
    <option value='2005'>2005</option>
    <option value='2006'>2006</option>
    <option value='2007'>2007</option>
    <option value='2008'>2008</option>
    <option value='2009'>2009</option>
    <option value='2010'>2010</option>
    <option value='2011'>2011</option>
    <option value='2012'>2012</option>
</select>
</div>

I know that it can be fixed with \t and \n. But I want to know if there is any way to do it automatically?

    It can be done with PHP’s tidy class. As well as PHP’s DOM extension.

    <?php

    $html = <<<HTML
<div>
    <select>
        <option value='2000'>2000</option>
        <option value='2001'>2001</option>
        <option value='2002'>2002</option>
        <option value='2003'>2003</option>
        <option value='2004'>2004</option>
        <option value='2005'>2005</option>
        <option value='2006'>2006</option>
        <option value='2007'>2007</option>
        <option value='2008'>2008</option>
        <option value='2009'>2009</option>
        <option value='2010'>2010</option>
        <option value='2011'>2011</option>
        <option value='2012'>2012</option>
    </select>
</div>
HTML;

    $dom = new DOMDocument();
    $dom->loadXML($html);

    $dom->formatOutput = true;
    echo $dom->saveHTML();
