I tried to get last-modified from the webpage header using get_headers().
<?php
$url = 'http://www.example.com';
print_r(get_headers($url));
print_r(get_headers($url, 1));
?>
But I don't get result, and the code above says that
Warning: get_headers() has been disabled for security reasons in [...][...] on line 4
Warning: get_headers() has been disabled for security reasons in [...][...] on line 6
Does anyone knows how to fix this?
And how to get the headers of the webpage?
Exactly, I want to get the last-updated date or modified.
If that's not available, when the website was created.
