script I made to get the info for last.fm users

 

<?php
$lastfm[] = file_get_contents("http://www.last.fm/user/joffeman");
$lastfm[] = file_get_contents("http://www.last.fm/user/chaos2092");
for($a=0; $a<count($lastfm); $a++){
echo $lastfm[$a];
$filename = "lastfm.txt";
$b = fopen($filename, 'w');
fwrite($b, $lastfm[0]);
fwrite($b, $lastfm[1]);
fclose($b);}
sleep(10000);
?>

 

It spits out everything on the page, I need to parse out the username and plays and put it in a file in this format

 

Username - Plays

 

each one on a new line

 

the info is in the contents of the page I just need to know how to parse it out

 

 

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml" lang="en">

<head profile="http://purl.org/uF/2008/03/">

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

            <title>joffeman’s Music Profile – Users at Last.fm</title>       

    <link rel="search" type="application/opensearchdescription+xml" href="http://cdn.last.fm/opensearch.xml" title="Last.fm" />

            <meta name="description" content="Listen to joffeman’s personal radio station (481,212 tracks played).

Listen to Chaos2092’s personal radio station (38,123 tracks played)

 

Now how could I parse that out and if I put another account in it will put the info in a file to I would need to parse out both and put it in format like

 

joffeman - 481,212 tracks played

Chaos2092 - 38,123 tracks played

 

 

any help would be appreciated

looks like the number of plays is set in tags like this:

<span class="count"><span class="flip">1</span></span>

 

So u could use regex to get the value

$play_span = preg_match("/<span class=\/"count\/">(.*?)<\/span>/", $html, $matches);
$play_span = $matches[1];

// NOW STRIP THE SPAN TAGS (i'm sure there is a better way but im too tired to think
$erase_me = array("<span class=/"flip/">", "</span>");
$plays = str_replace($erase_me, "", $play_span);

 

that should work..

Like I wanna take this file

 

http://dl.dropbox.com/u/2967480/lastfm.txt

 

and I just wanna parse out the part on the 9th line

 

"            <meta name="description" content="Listen to Chaos2092’s personal radio station (38,123 tracks played). Chaos2092’s top artists: Converge, Dream Theater, Porcupine Tree. Favourite tags are alcoholics anonymous suite, awesome riff, doom metal. Get your own music profile at Last.fm, the world’s largest social music platform."/>"

This in your "for" loop should do the trick. I'm not sure if you ONLY wanted to save the username and plays in the text file??

$lastfm_info = preg_match("/<meta name=\"description\" content=\"Listen to (.*?)\)./", $lastfm[$a], $matches);
$lastfm_info = $matches[1];
$lastfm_info = str_replace(" personal radio station (", " - ", $play_span);

now this is what I have

 

<?php
$lastfm[] = file_get_contents("http://www.last.fm/user/joffeman");
$lastfm[] = file_get_contents("http://www.last.fm/user/chaos2092");
for($a=0; $a<count($lastfm); $a++){
echo $lastfm[$a];
$lastfm_info = preg_match("/<meta name=\"description\" content=\"Listen to (.*?)\)./", $lastfm[$a], $matches);
$lastfm_info = $matches[0];
$lastfm_info = str_replace("’s personal radio station (", " - ", $play_span);
$filename = "lastfm.txt";
$b = fopen($filename, 'w');
fwrite($b, $matches[$a]);
fwrite($b, $matches[$a]);
fclose($b);}
sleep(10000);
?>

 

It didnt return joffemans plays and it returned this in the file "Chaos2092’s personal radio station (38,123 tracks playedChaos2092’s personal radio station (38,123 tracks played"

 

I want it to be like

 

joffemans - 481,212

Chaos2092 - 38,123

it wasn't taking out that extra stuff in it. sorry i forgot to correct some stuff in the code.. and as far is it repeating the info, its because you are saving the $matches[$a] .. replace all your for loop with this.. i'm sorry i keep giving u bad code lol. but this should work. i looked it over.

 

foreach($lastfm as $value){
echo $value;
$lastfm_info = preg_match("/<meta name=\"description\" content=\"Listen to (.*?)\)./", $value, $matches);
$lastfm_info = str_replace("’s personal radio station (", " - ", $matches[0]);
$filename = "lastfm.txt";
$b = fopen($filename, 'w');
fwrite($b, $lastfm_info]);
fclose($b);
}

ok I fought with this thing for a while. the encoding is messed up it appears and i can't figure out how to work with that. But i did find a work around.. SO Here is the new code:

$lastfm[] = file_get_contents("http://www.last.fm/user/joffeman");
$lastfm[] = file_get_contents("http://www.last.fm/user/chaos2092");
foreach($lastfm as $value){
preg_match("/<meta name=\"description\" content=\"Listen to (.*?)\)./", $value, $matches);
$lastfm_info = explode(" personal radio station (", $matches[1]);
$lastfm_info = substr($lastfm_info[0], 0, -4) . " - " . $lastfm_info[1];
echo $lastfm_info;
$filename = "lastfm.txt";
$b = fopen($filename, 'a'); // NEEDS TO BE 'a' FOR APPEND
fwrite($b, $lastfm_info);
fclose($b);
}
sleep(10000);

I suggest just looking at random tutorials and using Google a lot. I've learned most of what I know thru those methods lol.

It's hard to learn everything with PHP if you don't use everything in PHP. There is a lot I don't know but the basics become easier to remember as u use it.
