在 PHP 中创建多个站点地图

Question

我有以下问题，我在数组中生成了站点地图的网址。所以数组有 60000 个条目。谷歌希望我创建 2 个站点地图，因为每个站点地图的限制为 50000 个条目。

我怎样才能用 php 做到这一点？我尝试过，但是循环停止并在其他文件中输入其他数据时遇到问题。到目前为止，这是我的代码。

// $data is array with the urls
$count_array = count($data);
$maxlinksinsitemap = 50000;
$numbersofsitemap = ceil($count_array / $maxlinksinsitemap);

for($i = 1; $i <= $numbersofsitemap; $i++) {
    $cfile = "sitemap_" .$i . ".xml";
    $createfile = fopen($cfile, 'w');
    $creat = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
    $creat .= "<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"\n";
    $creat .= "xmlns:image=\"http://www.sitemaps.org/schemas/sitemap-image/1.1\"\n";
    $creat .= "xmlns:video=\"http://www.sitemaps.org/schemas/sitemap-video/1.1\">\n";
    $creat .= "<url>\n";
    $creat .= "<loc>http://www.urltosite.com</loc>\n";
    $creat .= "<priority>1.00</priority>\n";
    $creat .= "</url>\n";


    $creat .= "</urlset>";  
    fwrite($createfile, $creat);    
    fclose($createfile);


}

我需要一个动态的解决方案，

感谢帮助。

array_chunk是你的朋友：

$data = array_chunk($data, 50000);

foreach ($data as $key => $value)
{
    $cfile = 'sitemap_' . $i  . '.xml';
    $createfile = fopen($cfile, 'w');

    fwrite($createfile, "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
    fwrite($createfile, "<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"\n");
    fwrite($createfile, "xmlns:image=\"http://www.sitemaps.org/schemas/sitemap-image/1.1\"\n");
    fwrite($createfile, "xmlns:video=\"http://www.sitemaps.org/schemas/sitemap-video/1.1\">\n");

    foreach ($value as $url)
    {
        $creat = "<url>\n";
        $creat .= "<loc>" . $url . "</loc>\n";
        $creat .= "<priority>1.00</priority>\n";
        $creat .= "</url>\n";

        fwrite($createfile, $creat);
    }

    fclose($createfile);
}

可使用开箱即用的可变数量的站点地图。
