This model besides displaying availability has a modal with all the information.

github library colorbox

  

If you do not want to use the colorbox library, you can use a modal only with CSS

In this case remove the references and the script that is in the head section and put this CSS

      .modalDialog {
      position: fixed;
      font-family: Arial, Helvetica, sans-serif;
      top: 0;
      right: 0;
      bottom: 0;
      left: 0;
      background: rgba(0, 0, 0, 0.8);
      z-index: 99999;
      opacity: 0;
      -webkit-transition: opacity 400ms ease-in;
      -moz-transition: opacity 400ms ease-in;
      transition: opacity 400ms ease-in;
      pointer-events: none;
    }
    .modalDialog:target {
      opacity: 1;
      pointer-events: auto;
    }
    .modalDialog > div {
      width: 700px;
      height: 600px;
      position: relative;
      margin: 10% auto;
      padding: 5px 20px 13px 20px;
      border-radius: 10px;
      background: #fff;
      background: -moz-linear-gradient(#fff, #999);
      background: -webkit-linear-gradient(#fff, #999);
      background: -o-linear-gradient(#fff, #999);
      overflow: scroll;
    }
    .close {
      background: #606061;
      color: #FFFFFF;
      line-height: 25px;
      position: absolute;
      text-align: center;
      width: 24px;
      text-decoration: none;
      font-weight: bold;
      -webkit-border-radius: 12px;
      -moz-border-radius: 12px;
      border-radius: 12px;
      -moz-box-shadow: 1px 1px 3px #000;
      -webkit-box-shadow: 1px 1px 3px #000;
      box-shadow: 1px 1px 3px #000; 
    }
    .close:hover { background: #00d9ff; }
    .child { position:fixed;}
    .parent { position:absolute; }

and the final part of PHP replaces these two lines

    echo "<br><a class='inline' href=\"#inline_content\" title=\"Whois ".$dominio."\">Mostrar informações</a><br>";
    echo "<div style='display:none'><div id='inline_content' style='padding:10px; background:#fff;'><pre>".$result."</pre></div></div>";

By

    echo "<br><a href=\"#openModal\">Mostrar informações</a><br>
    <div id=\"openModal\" class=\"modalDialog\">
         <div class=\"parent\">
              <div class=\"child\"><a href=\"#close\" title=\"Close\" class=\"close\" id=\"fixedContainer\">X</a>
               </div>
               <p><pre>".$result."</pre></p>
          </div>
    </div>";
