php file_get_contents（）显示页面而不是html源代码

Question

I've got this piece of code, which should fetch the source code of the website.

$homepage = file_get_contents('http://homepage.com');
echo $homepage;

Instead of actually giving me the source code.. It's shows me the page that I'm trying to get the source code from.

Answer 1

Either use htmlentities or change the content type.

$homepage = file_get_contents('http://homepage.com');
echo htmlentities($homepage);

or

header('Content-type: text/plain');
$homepage = file_get_contents('http://homepage.com/');
echo $homepage;
