php - file_get_contents is not working for some url

Question

I use file_get_contents in PHP. In the below code in first URL works fine but the second one isn't working.

$URL = "http://test6473.blogspot.com";
$domain = file_get_contents($URL);
print_r($domain);


$add_url= "http://adfoc.us/1575051";
$add_domain = file_get_contents($add_url);
echo $add_domain;

Any suggestions on why the second one doesn't work?

Answer 1

URL which is not retrieved by file_get_contents, because their server checks whether the request come from browser or any script. If they found request from script they simply disable page contents.

So that I have to make a request similar as browser request. So I have used following code to get 2nd url contents. It might be different for different web server. Because they might keep different checks.

Even though why dont you try to use following code! If you are lucky this might work for you!!

function getUrlContent($url) {
    fopen("cookies.txt", "w");
    $parts = parse_url($url);
    $host = $parts['host'];
    $ch = curl_init();
    $header = array('GET /1575051 HTTP/1.1',
        "Host: {$host}",
        'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language:en-US,en;q=0.8',
        'Cache-Control:max-age=0',
        'Connection:keep-alive',
        'Host:adfoc.us',
        'User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36',
    );

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
    curl_setopt($ch, CURLOPT_COOKIESESSION, true);

    curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
    curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

$url = "http://adfoc.us/1575051";
$html = getUrlContent($url);

Thanks everyone for the guidance.
