 ];

<p>I want to perform some search task like url and duration so as to display in seperate coloumn but when I perform Regx for http then nothing print on html.</p>

<p>Here is my rough PHP code:</p>

<pre><code>$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://carouselinfo.com/contents.js');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 $contents = curl_exec ($ch);
 $contents = json_encode($contents,true);
 curl_close($ch);
 echo $contents;

 $reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
 if (preg_match_all($reg_exUrl,$contents,$url))
{
    echo '&lt;br/&gt;';
    echo $url;
}
</code></pre>
