Check URL on PHP

<?php $domain = 'http://google.ru'; if(preg_match('/[^0-9a-z-_A-Z:/.]/is', $domain)!=0){ include("idna_convert.class.php"); $IDN = new idna_convert(array('idn_version' =----> '2008')); $domain=$IDN->encode($domain); } $status=get_headers($domain); if(in_array("HTTP/1.1 200 OK", $status) or in_array("HTTP/1.0 200 OK", $status)){ echo $domain.' - доступен'; } ?>
The result of this PHP script will list all the http header by which you can judge the accessibility of the site
