Question

As I am new in PHP.Here is my js code

      var sites = [
 //Texte anime
  {url:" http://carouselinfo.com/canal/", duration:9},
 //Texte anime
  {url:" http://carouselinfo.com/canal-2/", duration:9}, 
  //Intro detallee
 {url:"http://carouselinfo.com/index-t1.html", duration:35},
 //CTA
 {url:"http://carouselinfo.com/index-t2.html", duration:35},
     //Football
  {url:"http://carouselinfo.com/twitter-ligue/", duration:100},  
 //Texte anime
  {url:" http://carouselinfo.com/canal-2/", duration:9},     
  //TrailersClub.com
  {url:"http://trailersclub.com/?lang=fr", duration:480},    
 //Heure
 {url:"http://carouselinfo.com/heure", duration:8},
 //Meteo
 {url:"http://carouselinfo.com/meteo", duration:12},
 //Texte anime
  {url:" http://carouselinfo.com/canal-cine/", duration:9},
 //Cine
 {url:"http://carouselinfo.com/cine/index-t1.html", duration:150},
  //Texte anime
  {url:" http://carouselinfo.com/canal-2/", duration:9}, 
 //Heure
 {url:"http://carouselinfo.com/heure", duration:8},
 //Meteo
 {url:"http://carouselinfo.com/meteo", duration:12},
 //Texte anime
  {url:" http://carouselinfo.com/canal-cine/", duration:9},
   //Cine

 ];

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.

Here is my rough PHP 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 '<br/>';
    echo $url;
}

Answer 1

First remove the json_encode call. Then apply following regex,

 /url\s*:\s*"([^"]+)"/

The code should look like.

$reg_exUrl = '/url\s*:\s*"([^"]+)"\s*,\s*duration\s*:\s*(\d+)/';
if (preg_match_all($reg_exUrl,$contents,$matches))
{
    print_r($matches[1]); // not using echo here
    print_r($matches[2]); 
}
