Hi, All, Sorry to trouble you, but I really can not handle this problem now. I want to call get_meta_tags() function to get meta-tags which site I want to know. I searched usage and I did like this: <?php // Call get_meta_tags to fetch meta_tags in brackets. $tags = get_meta_tags("http://www.example.com/"); //Echo meta content print $tags['keywords']; ?> But an errors occurred when the page run. Some information liked this: Warning: get_meta_tags(): php_network_getaddresses: gethostbyname failed in d:\apache\htdocs\meta_tag.php on line 3 Warning: get_meta_tags(http://www.pconline.com.cn): failed to open stream: No such file or directory in d:\apache\htdocs\meta_tag.php on line 3 My server is Apache 1.3.27 and PHP4.4.0 that run in Windows 2000 server. I want to ask if anybody can solve the problem, thanks so much. Best wishes, Jimmie
