How to get japanese wiki link from my english wiki link? - php

Question

Task: We have wikipedia English page and need to retrieve the same page address in Japanese.
suggested to parse http://en.wikipedia.org/wiki/Mini 4wd?action=raw results (there are other languages links in the bottom), but this way is too inefficient. Are there any other ways is the one real option?
We found some API in Wiki that seems fine for single word. but for two words like - Kamen rider, mini 4wd ... it doesn't work.
My code is not working
$url = 'https://en.wikipedia.org/w/api.php?action=query&prop=langlinks&format=json&lllimit=100&llprop=url&lllang=ja&titles=Kamen rider';
$url = rawurldecode(urlencode($url));
echo $url;
// outputs: https://en.wikipedia.org/w/api.php?action=query&prop=langlinks&format=json&lllimit=100&llprop=url&lllang=ru&titles=Mini+4wd
// and then the rest your logic whatever it is the rest
$header[] = "Accept: application/json";
$header[] = "Accept-Encoding: gzip";
$ch = curl_init();
curl_setopt( $ch, CURLOPT_HTTPHEADER, $header );
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$response = json_decode(curl_exec($ch));
/* echo '<pre>';
print_r($response);
echo '</pre>'; */
exit;

Answer 1

Two words doesn't work because its not properly formatted. Kamen<space>rider and mini<space>4wd has spaces. You need it to be converted first. Consider this example:
$url = 'https://en.wikipedia.org/w/api.php?action=query&prop=langlinks&format=json&lllimit=100&llprop=url&lllang=ru&titles=Mini 4wd';
$url = rawurldecode(urlencode($url));
echo $url;
// outputs: https://en.wikipedia.org/w/api.php?action=query&prop=langlinks&format=json&lllimit=100&llprop=url&lllang=ru&titles=Mini+4wd
// and then the rest your logic whatever it is the rest
$contents = file_get_contents($url);
$contents = json_decode($contents, true);
// echo '<pre>';
// print_r($contents);
// echo '</pre>';

Kindly try this code it works. Your $keywords = 'Mini 4wd';
$url = 'https://en.wikipedia.org/w/api.php?action=query&prop=langlinks&format=json&lllimit=100&llprop=url&lllang=ja&titles='.$keywords.'&redirects=';
$url1 = rawurldecode(urlencode($url));
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, $url1);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
// $output contains the output string
$output = curl_exec($ch);
$info = curl_getinfo($ch);
$exec = explode('"url":"',$output);
$exe = explode('",',$exec[1]);
$URL = $exe[0];
Output :
