get_file_contents URL issue...

**MadDog31** · Feb 16, 2004 13:05

Hey all,

Going off of what I did last week on the get_file_contents of a stock quote, a buddy of mine wondered if I could use PHP to pull a song name from his Shoutcast server site to display directly on his homepage.

Here's the skinny:

PHP Code:


<html> 

<head> 

  <title>Current Song Playing</title> 

</head> 

<body> 

<?php 



// Set variables for the station URL and name

    $stationurl = 'http://peatboxradio.darktech.org:8000/listen.pls';

    $stationname = 'Peatbox Radio';



    echo '<h1>Current Song Playing on '. $stationname . '</h1>'; 



// Get information

    $theurl   = 'http://peatboxradio.darktech.org:8000'; 

    $contents = function_exists('file_get_contents') ? file_get_contents($theurl) : implode('', file($theurl)); 

    if (!$contents) { 

        die('Unknown information'); 

    } 



    $pattern = '~Current Song: </font></td><td><font class=default><b>(\$[a-z]+)</b> ~iUs';



    if (preg_match($pattern, $contents, $match)) { 

        $currentsong = $match[1]; 

        echo '<p> Current song playing is: <strong>' . $currentsong . '</strong></p>'; 

    } else {

        echo 'Could not retrieve value <br />';

    }



// Acknowledge source 

    echo 'This information retrieved from <br /> 

           <a href="'.$theurl.'">'.$theurl.'</a><br /> 

           on ' . date('l jS F Y g:i a T'); 

?> 

</body> 

</html>

I'm trying to pull the 'Current Song' playing that's listed in this URL:

http://peatboxradio.darktech.org:8000/

I'm using file_get_contents to read in that page, however, it only works when I ditch the ':8000' from the URL, so I'm assuming there's issues w/ utilizing pages that are via certain ports. I know my code my be sketchy elsewhere (such as $pattern) but I just want to get past this port issue first. The above URL is the only way to get to the current song also.

I'm gonna head over to the Manual to see if I can find anything there, but wanted to post here to see if anyone has had issues w/ this before.

If you use file_get_contents() on a url, it goes to port 80. You will have better luck with fsockopen. That way you can open port 8000.

I'll have to do some reading up on fsockopen...loops pretty in-depth.

not hard.

Pseudocode:

fsockopen(location,port);
read contents into string;
close fsockopen;

use string.

PHP Code:


$fp = fsockopen('peatboxradio.darktech.org', 8000) or die('Connection failed');

$request = "GET /listen.pls HTTP/1.0\r\nHost: peatboxradio.darktech.org\r\nConnection: close\r\n\r\n";

fputs($fp, $request);    

$found   = false;

$header  = '';

$content = '';

while (!feof($fp)) {

    $data = fgets($fp, 4096);

    if (!$found) {

        $header .= $data;

        if (false !== ($data = strstr($header, "\r\n\r\n"))) {

            $data = substr($data, 4);

            $found = true;

        }

    }

    if ($found)

        $content .= $data;

}

fclose($fp);



// $content should now contain the file

Well I'm getting closer after that code however I'll have to play with it some more to get it to work properly. Thanks to both of you for assistance as always. I'll have to play w/ this some more when I have the opportunity.

Meanwhile, I need to learn about sessions.

On Chapter 20 in the PHP/MySQL Web Development book.
