Is it possible to avoid situations like this ?

akitchin Posted August 9, 2009 Share Posted August 9, 2009 how are you calling the function? are you just calling it as get_headers() without any parameters? if so, that's likely the problem since the first parameter in the function is required.

i-sultan Posted August 27, 2009 Author Share Posted August 27, 2009 Hi all I am sorry but solution may be interesting for someone... I solved this problem almost 2 weeks ago but forgot a bit so now my solution is just use function gethostbyname() to get IP address of host and then use get_headers() function... 1#!/usr/bin/php -q 2 <?php 3 $links = array( 4 'www.kg', 5 'www.inkar.info', 6 'www.sdpk.info', 7 'www.sdpk.kg', 8 'www.google.com', 9 'www.google.tre' 10 ); 11 12 for ( $i = 0; $i < count($links); $i++ ) { 13 $ip = gethostbyname($links[$i]); 14 15 $valid_link = 'http://'.$ip; 16 17 if ( preg_match('/^\d+/', $ip) == 0 ) { 18 print "Unable to resolve address...\n"; 19 20 continue; 21 } 22 23 printf("Link:%s; IP:%s\n", $links[$i], $ip); 24 print_r(get_headers($valid_link)); 25 } thanks for all !!!
