Ajutor pagina web

[Levy]

Cum as putea sa citesc datele de pe un server radio si sa le afisez intr-o pagina web.
Datele care ma intereseaza sint doar numele DJ-ului si numarul de ascultatori, eventual si numele melodiei curente.

Are cineva solutie pentru asta ??

[Levy]

Am gasit datele care trebuiesc citite din server.
Ele se pot gasi aici.

Primul numar este numarul curent de ascultatori.
Al doilea numar nu stiu ce inseamna.
Al treilea numar afiseaza numarul maxim de ascultatori care au fost vreodata pe server.
Al patrulea numar nu stiu ce inseamna.
Al cincilea numar este bitrateul cu care transmite DJ-ul.
Si la final este afisat numele DJ-ului.

Cum se pot afisa (citite separat) aceste date pe o alta pagina ?

[Levy]

Iar la aceasta pagina se poate gasi numele melodiei redate in acest moment.
In cazul in care nu se vede nimic din numele melodiei, DJ-ul are setarile ca sa nu se vada numele melodiei redate.

Cu PHP ar merge, depinde cât de mult te pricepi la PHP și dacă serverul tău rulează PHP.
De exeplu funcția file_get_contents încarcă întreg conținutul unui fișier într-o variabilă, variabilă pe care o poți prelucra cu alte funcții și să afișezi doar ce ai nevoie.

Code: Select all

<?php
$radio = file_get_contents('http://212.108.200.53:7210/7.html');
echo $radio;
echo substr($radio, 0, 2);
?>

[Levy]

Nu ma pricep deloc la PHP, de aia am cerut ajutor aici

Am bagat liniile respective in pagina, insa nu afiseaza nimic in pagina, plus ca afisarea ar trebui sa se produca la un interval prestabilit 5-10 secunde..

The only problem with file_get_contents is that some web hosts have url access blocked in the file methods, for security reasons.

Da, se pare că file_get_contents nu merge pe orice pagină...

[Levy]

Nu avem nici un "meserias"in javascript sau PHP pe aici ?

[Levy]

Am gasit doua script-uri care promit sa face cea ce vreau eu, insa nu inteleg cum se foloseste, direct embedd in pagina nu functioneaza...

Are cineva idee cum se adauga aceste PHP-uri intr-o pagina web ??

[Levy]

Am mai gasit ceva aici, dar cu datele introduse corect nu functioneaza.

Desi am facut totul dupa indicatiile din acea pagina.

Code: Select all

<!DOCTYPE html>
   <html>
   <head>
      <title>My Radio Station</title>
   </head>
   <body>
     
      <h1 data-shoutcast-value="servertitle"></h1>
     
      <p>Now Playing: <span data-shoutcast-value="songtitle"></span></p>
      <p>Listeners: <span data-shoutcast-value="currentlisteners"></span>/<span data-shoutcast-value="maxlisteners"></span></p>
     
      <h2>You just missed</h2>
      <ul id="played"></ul>
     
     
      <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
      <script src="jquery.shoutcast.easy.min.js?host=212.108.200.53&port=7210"></script>
   </body>
   </html>

[Levy]

Pentru serverele shoutcast v2 am gasit solutie functionala:

Code: Select all

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

<meta name="robots" content="noindex">
  <title>My Radio Station</title>
</head>
<body>
<title>My Radio Station</title>

  <h1 data-shoutcast-value="servertitle"></h1>
 
  <p>Now Playing: <span data-shoutcast-value="songtitle"></span></p>
  <p>Listeners: <span data-shoutcast-value="currentlisteners"></span>/<span data-shoutcast-value="maxlisteners"></span></p>
 
  <h2>You just missed</h2>
  <ul id="played"></ul>
 
 
  <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="https://rawgit.com/Wavestreaming/jquery-shoutcast/master/jquery.shoutcast.easy.min.js?host=tachyon.shoutca.st&port=8098"></script>

</body>
</html>

Dar nu functioneaza pe serverele Shoutcast v1.
Inca nu am gasit solutia pentru acestea.

Un test functional cu un server v2 se poate vedea aici.
