this code just works fine in server but not in local wamp server
I think you need to turn on the following PHP parameter.
allow_url_fopen = On
You can find this in the php.ini file.
If you are using WAMPServer then you can also turn this on using the wampmanager icon menus as follows
left_click wampmanager icon -> PHP -> PHP Settings -> Allow URL Fopen
I had a closer look at your code.
I would imagine that the data in $tag->getAttribute('src') does not have a full url at least in one case which is causing your error.
It is probably using a relative address like img/imagename.png and not http://example.com/img/imagename.png
That would explain the error message nicely.
Try adding an echo of what you are getting out of that statement.
$tags = $doc->getElementsByTagName('img');
foreach ($tags as $tag) {
echo $tag->getAttribute('src');
$data = get_headers($tag->getAttribute('src'),1);
$op7=''.$tag->getAttribute('src').'';
echo $op7;
}
The value of $op7 is /files/img/nav/nav_02.png according the the screenshot you linked. That is a root-relative URL, get_headers() requires an absolute URL (starting with 'http://').
You need to glue the domain you are querying (http://www.brobible.com) to the root-relative path of the image so that it looks like
get_headers('http://www.brobible.com'.$tag->getAttribute('src'),1)
Keep in mind this will now only work with root-relative paths; you will probably want to check for absolute and relative paths before you assume they need the domain glued on this way.
