Symfony - how to save a xml file? [duplicate] - symfony

Question

This question already has an answer here:
How let Twig write the HTML output to a file, instead to a browser?
(1 answer)
Closed 1 year ago.
In this code below I have just generated in the browser a .xml page that shows a specific sitemap of the distributor route.
I just want to save this generated .xml in a file (in /public/sitemap folder).
what I have, and what I WANT TO USE, are only this two (like the render at the bottom of the Controller):
the urls array (see: inside the foreach)
the template of the xml file
I have already found a possible solution but is not pratical, and is not what I want. (Create new xml file and save in system using symfony2.8)
Controller:
/**
* #Route("/sitemap/sitemap.xml", name="distributor_sitemap", defaults={"_format"="xml"})
*/
public function getSitemap(Request $request) : Response
{
$urls = [];
$hostname = $request->getSchemeAndHttpHost();
// return an array of routes
$routes = $this->sitemapService->getThreeRoutesByIndexes('/distributor/');
foreach ($routes as $route){
$urls[] = array('loc' => $this->generateUrl($route));
}
// save locally the file
// -----------------------------
// ----- add the code HERE -----
// -----------------------------
// return response in XML format
$response = new Response(
$this->renderView('sitemap/sitemap.html.twig', array(
'urls' => $urls,
'hostname' => $hostname
))
);
$response->headers->set('Content-type', 'text/xml');
return $response;
}
Template:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
{% for url in urls %}
<url>{# check if hostname is not alreay in url#}
<loc>{%if url.loc|replace({hostname:''}) == url.loc%}{{hostname}}{{url.loc}}{%else%}{{url.loc}}{%endif%}</loc>
{% if url.lastmod is defined %}
<lastmod>{{url.lastmod}}</lastmod>
{% endif %}
{% if url.changefreq is defined %}
<changefreq>{{url.changefreq}}</changefreq>
{% endif %}
{% if url.priority is defined %}
<priority>{{url.priority}}</priority>
{% endif %}
{% if url.image is defined and url.image is not empty %}
<image:image>
<image:loc>{%if url.image.loc|replace({hostname:''}) == url.image.loc%}{{hostname}}{{url.image.loc}}{%else%}{{url.image.loc}}{%endif%}</image:loc>
<image:title>{{ url.image.title }}</image:title>
</image:image>
{% endif %}
</url>
{% endfor %}
The Browser result
So again the final result is to generate a .xml file in the /public/sitemap folder, and this file must contain the urls array informations disposed by the template, as it is showed in the browser. ( all the code that to this should be added in the Controller near the ---- add the code HERE ----)

Assign the content of your render template to a var, then write it in the file you want.
/**
* #Route("/sitemap/sitemap.xml", name="distributor_sitemap", defaults={"_format"="xml"})
*/
public function getSitemap(Request $request) : Response
{
$urls = [];
$hostname = $request->getSchemeAndHttpHost();
// return an array of routes
$routes = $this->sitemapService->getThreeRoutesByIndexes('/distributor/');
foreach ($routes as $route){
$urls[] = array('loc' => $this->generateUrl($route));
}
// save locally the file
$xmlContent = $this->renderView('sitemap/sitemap.html.twig', array(
'urls' => $urls,
'hostname' => $hostname
));
// Assuming the folder sitemap exists in `public`
$path = $this->getParameter('kernel.project_dir') . '/public/sitemap/sitemap.xml';
$fileSystem = new Filesystem();
$fileSystem->dumpFile($path, $xmlContent);
// -----------------------------
// ----- add the code HERE -----
// -----------------------------
// return response in XML format
$response = new Response($xmlContent);
$response->headers->set('Content-type', 'text/xml');
return $response;
}
