如何使用

1 通过composer安装

composer require webarchitect609/sitemap

2 创建writer实例

$sitemapWriter = new \WebArch\Sitemap\SitemapWriter('http://example.org', '/var/www/example.org/htdocs');

3 对于简单使用,直接将urls添加到writer

use WebArch\Sitemap\Enum\ChangeFreq;
use WebArch\Sitemap\Model\Url;

$url1 = (new Url('/index.php'))->withChangefreq(ChangeFreq::CHANGE_FREQ_DAILY)
                               ->withPriority(0.9)
                               ->withLastmod(
                                   DateTimeImmutable::createFromFormat(
                                       'Y-m-d H:i:s',
                                       '2018-07-13 10:37:48'
                                   )
                               );

$url2 = (new Url('/news/index.php'))->withChangefreq(ChangeFreq::CHANGE_FREQ_HOURLY);

$sitemapWriter->addUrl($url1)
              ->addUrl($url2);

4 对于更复杂的情况,可以创建所需数量的sitemap并交给writer

$newsSitemap = new \WebArch\Sitemap\Model\Sitemap('/sitemap_news.xml');

$newsSitemap->addUrl(
                (new Url('/news/detail/1/'))
            )
            ->addUrl(
                (new Url('/news/detail/2/'))
            )
            ->addUrl(
                (new Url('/news/detail/3/'))
            );

$sitemapWriter->addSitemap($newsSitemap);

5 可以应用附加选项以遵守sitemap限制

/**
 * Limit maximum urls count. When it's overflowed an `\WebArch\Sitemap\Exception\UrlCountLimitException` would be issued.
 * It's ON by default.
 */
$newsSitemap->getUrlSet()->withMaxUrlCount(50000);

/**
 * Limit maximum file size
 * It's OFF by default.
 * WARNING: it WILL slow down everything: after adding new url estimated size calculations would be executed.
 * (Hope to get rid of this in the future)
 */
$newsSitemap->getUrlSet()->withMaxXmlSizeBytes(10*1024*1024);

6 然后让它工作

$sitemapWriter->write();

在此之后,所有内容都将写入sys_get_temp_dir()。如果没有错误,新版本的sitemapindex和所有sitemap将被部署到其最终目的地$sitemapWriter->getBaseDir(),并将文件权限更改为允许任何人读取。

运行单元测试

composer test
