title: imap_search() with for() will not search for sender
body: <p>The loop (<code>$zeile[$i]</code>) will not be executed, when it is in the <code>imap_search()</code> function.</p>
  
  <p>The syntax (<code>$inbox, 'FROM " ' . $zeile[$i] . ' " '</code>) is like a lot of examples I have found.
  Outside of this codeblock it works well. 
  But inside even the line on the bottom (<code>echo "@" .$zeile[$i]."&lt;br&gt;";</code>) will not show anything.
  With a single var (<code>$test = "domain.de";</code>) it works though.</p>
  
  <pre><code>$test = "domain.de";
  $zeile = file("blacklist.txt");
  for ($i=0;$i &lt; count($zeile); $i++) {
      $emails = imap_search($inbox, 'FROM " ' . $zeile[$i] . ' " ');
      if ($emails) {
          foreach ($emails as $email_number) {
              imap_setflag_full($inbox, $uid, "\\Seen", ST_UID);
              echo "@" .$zeile[$i]."&lt;br&gt;";
          }
      } // if emils
  } //Dateischleife
  imap_close($inbox, CL_EXPUNGE);
  </code></pre>
