Help with php .... Some heavy credits for solving it :)

Hey guys I am stuck in a tricky situation:

I have a list of mp3 url's.....However b4 trying to use them into my mp3player, I just want to make sure whether the url's are valid mp3 urls or not (by valid i mean, some might be dead too).

Here are the 4 cases:

[B]  [I]1) // Resource #2 Ok -> $fixed_url = "http://www.adoptedaustralian.net/glorylibertymix/nanowrimo/05%20Damien%20Rice%20-%20Older%20Chests.mp3";[/I]
  [I]2) // Blank Timed Out -> $fixed_url = "http://bellx1.davejeffery.com/Upload/data/Damien%20Rice-I%20rememer-Damien%5C%27s%20part%20only.mp3";[/I]
  [I]3) // Blank Not found -> $fixed_url = "http://info.showroomseven.com/SHOWROOM_SEVEN/Amber/Eskimo.mp3";[/I]
  [I]4) // Resource id#2 Ok but not mp3 ->$fixed_url = "http://www.flashbacked.net/mp3/04%20Wish%20You%20Were%20Here.mp3";

[/I]I validate them using this code:

[/B]

$fixed_url = "Choose one of the url from above";
[B]  $urlresponse = @fopen($fixed_url, "r");
  [U]echo[/U] $urlresponse;[/B]

Now the problem is that only 1st url in the list is a valid mp3.

2) and 3) are dead links for which, if u type them directly in the browser u will get timed out or do not exits.

Now the tricky one is the 4th one:
It ends with .mp3 extension, also returns a response to the code, but actually its an html page.
Just type the 4th url in the browser and you would know.

Now I want to filter these cases too. Can someone help me here ??

Points gauranteed to the first correct answer.

This is in the wrong forum. It should be in the 'Programming Help' forum.

oracle, please don't re-post a thread in another forum, as we can easily move threads between forums.

what you need to do with your fopen is if it succeeds, read a few lines, until you find one with the content type on it, if it application/octet-stream or you could check if it returns a line such as "Content-disposition: attachment; filename=xxxxx.mp3"

if it doesnt chances are its not an mp3

Lemme try it out, and will get back here.

However i don't think it is best of the solution. Anyways let me see.

thanx

i would suggest reading (a part of) the file and then do something like

if(preg_match("/<[h|H][t|T][m|M][l|L][.|\n]*>/", $data)) $ishtml = true;
else $ishtml = false;
