PHP Header question

[rckehoe]

Hello,

 

I am not sure where to start looking for this, but I was wondering how I would obtain the header information of a specified URL using PHP... For example.

 

I am having users specify their XML feed URL and I want to be able to check the URLS data-type and make sure that it is a XML feed... I don't want to use the domain extension, because sometimes it will be a PHP extension or an ASP extenstion...

 

get my drift?

I've never come across a method of gathering headers myself... (not saying it isn't possible, but I haven't heard of it).

 

Can't you just demand that the xml file has <?xml version="1.0" encoding="utf-8"?> at the top? Most should anyway tbh, if they're valid xml.

Are you looking for get_headers function?

Well I'll be damned.

You want to get the Content-Type of a HTTP header of a URL ?

 

Like that : http://web-sniffer.net/

 

You can use cUrl to do that like this :

 

<?php
$timeout = 10;
$ch = curl_init("http://www.somesite.com/somepage.php");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.64');
curl_setopt($ch, CURLOPT_HEADER, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output;
?>

the get_headers function works great. Thank you.
