header - Get Content-Type of requested url in php

Question

Using php how would I be able to define the variable $type into the content-type of http://www.example.com

For example: $type defined as "text/html"

So far this is what i am working with:

<?php
$url = 'http://www.example.com';
print_r(get_headers($url));
print_r(get_headers($url, 1));
?>

The code may be changed as much as needed

Answer 1

Have you tried:

$type = get_headers($url, 1)["Content-Type"];

As noted in comments by @Michael, this syntax won't work without a very current version of PHP.

Have you also tried:

$headers = get_headers($url, 1);
$type = $headers["Content-Type"];
