including a specific html element from another site using php echo

Question

im brand new to php (started yesterday) ive got a decent background of html/css and a bit of js so i though id give it a shot.

Im trying to build a simple application to teach myself php and i wanted to reference a piece of html from another site, for example the div :

<div id="name"> <p>Sam</p> </div> on the page "http://www.example.com/about.php"

what i was trying was <?php echo file_get_contents("http://www.example.com #name"); ?> is that the right way to go about it ?

i was also couldnt work out if it was better to use include echo or echo file_get_contents

sorry for such a basic question

That'll never work. you can't request just 'part' of a document. You have to transfer the entire page, then use a DOM operation to extract just the portion you want. — Marc B, Oct 09 '12 at 18:24

That can be done with DOMDocument, here's an example:

$doc = new DOMDocument();
$doc->loadHTMLFile('http://example.com/');

// get the element that has id=name
$result = $doc->getElementById('name');

echo $result->nodeValue; // prints: Sam

// or print out $result to see all of the properties
print_r($result);

seems to work fine, Thank very much !, do you know if it would work if i swapped out the url after loadHTMLfile with a variable ? – sam Oct 09 '12 at 20:02
