PHP Locally

[Darwinian]

OK, I'd like to be able to get the following code to run on my computer rather than my server.

It's code to download a youtube clip and save it as an flv file and, on my server, it works brilliantly. However, I'd like to somehow include it as a feature for my media player so that users can do the same but on their own P.C.

Any ideas?

Code:

<?php

class youtubegrabber{

    var $youtube_video_url;
    var $test;
    var $final_flv_filename;
    var $cookies_path;
    var $curl_headers;
    var $flv_url;

    function __construct($youtube_video_url, $final_flv_filename, $test = 0){
        $this->youtube_video_url = $youtube_video_url;
        $this->test = $test;
        $this->final_flv_filename = $final_flv_filename;
        
        $this->youtube_video_id = $this->get_youtube_video_id();
        
        $this->cookies_path = "cookies.txt";
        $clear_cookies = $this->clear_cookies();
        
        $this->curl_headers = array(
            "Accept-Language: en-us",

            "Connection: Keep-Alive",
            "Cache-Control: no-cache"
            );
            
        $this->flv_url = $this->get_flv_url();
        
        $save_binary = $this->get_curl_binary();
        $clear_cookies = $this->clear_cookies();
    
    }
    
    function get_youtube_video_id(){
        $thearray = explode("watch?v=", $this->youtube_video_url);
        return $thearray[1];
    }
    
    
    function clear_cookies(){
    
        if(file_exists($this->cookies_path)){
            unlink($this->cookies_path);
        }
        
        $ourFileName = $this->cookies_path;
        $ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
        fclose($ourFileHandle);
        
    }
    
    function get_flv_url(){
    
        $html = $this->curl_get_url($this->youtube_video_url);

What is it you're trying to do, execute the PHP locally from your app, or convert the code to Delphi to run inside your app?

Ideally convert it to Delphi but anyway to get it to work locally is ok with me.

Well, I would think that you'd be able to install a PHP interpreter locally to get it to work, though I agree with you that getting it to work natively in your app is better.

Unfortunately, I know fuck all about Delphi's APIs - but the PHP code itself is fairly trivial (though is somewhat obtuse in parts). All it's doing is retrieving a given URL, extracting the URL of the FLV video stream, and then downloading that to a file. Assuming Delphi has reasonable APIs for retrieving data by URL, HTTP/XML manipulation and string matching, it shouldn't be too difficult to replicate.

I'll have to study it a bit then :S

Hey, all you gotta do is port your app to C or Java and I can be more help.

Easiest way to run PHP (on Windows) is to install an apache server and PHP. You can do this easily using XAMPP: http://www.apachefriends.org/en/xampp-windows.html

Then you should just be able to create the PHP file in the apache directory and access it through the browser using http://localhost/path/to/file.php

Edit: Looking at the code, it seems to me it just fetches the HTML and extracts the .flv URL from that, then saves that as the file. Should be easy to do with any HTML library.

[Jackalope]

You don't even need Apache. You can execute the script directly by calling the PHP interpreter directly.

Yeah, my bad. I thought he just wanted to run the file, and the easiest (i.e. most non-technical) way to do that is via Apache since it handles everything for you.

You could always translate it to C and then compile it into a command line executable that I could run like this..

youtubedownload.exe "http://www.youtube.com/watch?v=pTtsn2Srm3E" "C:\test.flv"



If you're not too busy

I'd give you a write-up in the credits
