How can I check if a URL exists via PHP?
...ders = @get_headers($file);
if(!$file_headers || $file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}
else {
$exists = true;
}
From here and right below the above post, there's a curl solution:
function url_exists($url) {
return curl_init($url) !== false;
}

WebKit/Blink's (Safari/Chrome) default behaviour on MacOS since 10.7 (Mac OS X Lion) is to hide scroll bars from trackpad users when they're not in use. This can be confusing ; the scroll bar is often the only visual cue that an element is scrollable.
