Try this

<?php
    function extract($url){
    $sites_html = file_get_contents("$url");
    $html = new DOMDocument();
    $$html->loadHTML($sites_html);

      foreach ($html->loadHTML($sites_html) as $row)
      {
       if($row=="wanted_url") 
       {
         echo $row;
       }
     }
 }
?>

you can use regex: try this code

$matches = [[],[]];
preg_match_all('/\"wanted_url\": \"([^\"]*?)\"/', $sites_html, $matches);
foreach($matches[1] as $match) {
    echo $match;
}

this will print all urls with wanted_url tag

you said that this document contains "key": "value" – HSLM Sep 18 '17 at 09:54
@Emmanuel try the code now be sure that $sites_html contains the urls as you said they are like: "key": "value" if they are like that you can use this code – HSLM Sep 18 '17 at 09:56
@hassan thanks in advance, but it is not working, if u can run the full code and check it. – Emmanuel Sep 18 '17 at 12:32
Hi @Emmanuel this is a working code from my terminal $urls = '"url1": "http://notneeded.com", "url2": "http://notneeded.net", "wanted_url": "http://wantedurl1.com", "wanted_url": "https://wantedurl3.com"'; $matches = [[], []]; preg_match_all('/\"wanted_url\": \"([^\"]*?)\"/', $urls, $matches); foreach($matches[1] as $match) {echo $match . ', '; } http://wantedurl1.com, https://wantedurl3.com, ⏎ >>> – HSLM Sep 18 '17 at 16:55
