Wikimedia api and php - php

Question

I am using the Wikimedia api and php. I need to get first main image from article and all text in article. I have got code for it, but it takes only short info and very little picture. I tried to change many parameters, but it is not working.
Code is here:
function get_wiki_url($title) {
$context = stream_context_create(array(
'http' => array(
'method'=>"POST",
'content' => $reqdata = http_build_query(array(
'action' => 'opensearch',
'search' => $title,
'prop' => 'info',
'format' => 'xml',
'inprop' => 'url'
)),
'header' => implode("\r\n", array(
"Content-Length: " . strlen($reqdata),
"User-Agent: MyCuteBot/0.1",
"Connection: Close",
""
))
)));
if (false === $response = file_get_contents("http://ru.wikipedia.org/w/api.php", false, $context)) {
return false;
}
//парсим строку
$xml = simplexml_load_string($response);
return $xml->Section->Item;
}
var_dump ($pages_data = get_wiki_url("article header"));

Answer 1

Your query appears to be running a search for $title (parameter action=opensearch); if you want the article and main image (I presume you want HTML, not wikitext), you need to use action=parse -- see the Mediawiki parse documentation.
Example URL for getting the Hyperloop page:
http://ru.wikipedia.org/w/api.php?action=parse&format=xml&page=Hyperloop
The documentation has details on all the options available.
