Hello reader! If you have a to check the url is correct or not (not giving the status 404), Then you can get all the details of any url by using 'get_headers' in print_r. Let's see the example below:-0

<?php
 stream_context_set_default(
    array(
        'http' => array(
            'method' => 'HEAD'
        )
    )
);
print_r(get_headers('http://example.com'));

// Output:-
Array
(
    [0] => HTTP/1.1 200 OK 
    [Date] => Sat, 29 May 2004 12:28:14 GMT
    [Server] => Apache/1.3.27 (Unix)  (Red-Hat/Linux)
    [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
    [ETag] => "3f80f-1b6-3e1cb03b"
    [Accept-Ranges] => bytes
    [Content-Length] => 438
    [Connection] => close
    [Content-Type] => text/html
)

Now you see in the output [0] => HTTP/1.1 200 OK So by this way you have all the details of any url and check with the several parameters.
