[HELP] Getting info off an external page and putting it onto my own.

[lolwut]

Hiii,

I am looking for help with trying to get hold of a bit of source code on a web page. For examples sake, let's say it's YouTube, and I want to get the video description.

For example. Let's say the URL is http://youtube.com/watch?v=p0DWvta7pg0
and I want to get this code off the page and onto mine:

              <span id="vidDescBegin"> 
This is like the video description.
</span> 

I want to do this as my site has a few of my favourite YouTube videos on it and I would like for the video descriptions to come up below the videos.

I'm not sure if you'd do

<?php
file_get_contents("http://youtube.com/watch?v=p0DWvta7pg0",<span id="vidDescBegin>,</span>");
 ?>

or something like that, any help appreciated greatly. will rep if i can.

The easiest way is to use a little function that it easily available on the Internet called "get_string_between". Here is how you'd do it:

<?php
/* String function */
function get_string_between($string, $start, $end){
        $string = " ".$string;
        $ini = strpos($string,$start);
        if ($ini == 0) return "";
        $ini += strlen($start);  
        $len = strpos($string,$end,$ini) - $ini;
        return substr($string,$ini,$len);
} 
/* End string function */

$yt = file_get_contents("URL OF YOUTUBE PAGE");
$spancontents = get_string_between($yt, "<span id='whatever-it-is'>", "</span>");
?>

Easier code

$tehsource = file_get_contents("www.youtube.com etc");
$step1 = explode('<span id="vidDescBegin">', $tehsource);
$step2 = explode('</span>', $step1[1]);
$youtubedescription = $step2[0];

Genral purpous gabbing code i wrote a while back

//Genral Purpos content Grabbing Function.    
//By Carl (http://thybag.co.uk)
function GrabContent($url,$prefix,$suffix){
        // get page contents
        $page = file_get_contents($url);
        //search for matches
        preg_match_all("#".$prefix."(.+?)".$suffix."#is", $page, $finds);
        // [0] matches + param  - [1] matches
        return $finds[1];
}
//test it on habbox

$foundarray = GrabContent("https://habbox.com/site/","<div class='section' ><div class='shadow' ><div class='menuBox' >",'</div></div></div>');

print_r ($foundarray); 

It returns a multi level array of everything maching the search paramiters, so if theres a repeteing part u can grab each one of them seperatly

If it's just basic html, but I see your wanting PHP.

Err no. He does not want to play the video on his site.
