Question

Here is my code :

function get_data($url)
{
$ch = curl_init();
$timeout = 15;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERAGENT, random_user_agent());
$data = curl_exec($ch);
curl_close($ch);
return $data;
}

//Grab HTML
$urllist = fopen("links.txt", "r+");
for ($j = 0; $j <= 50; $j++)
{
$post = rtrim(fgets($urllist));
echo $post;
$html = get_data($post);
echo $html;

Problem : when I use get_data("http://url.com") I get the right data in html. But when I pass the url using a variable, $html returns nothing.

$post holds the right url as I checked it. Isnt it the right way to use get_data($post);

Curl info gives :

I get this :

array(20) { 
["url"]=> string(68) "http://secret-url.com" 
["content_type"]=> string(9) "text/html" 
["http_code"]=> int(301) 
["header_size"]=> int(255) 
["request_size"]=> int(340) 
["filetime"]=> int(-1) 
["ssl_verify_result"]=> int(0) 
["redirect_count"]=> int(0) 
["total_time"]=> float(0.095589) 
["namelookup_time"]=> float(0.012224) 
["connect_time"]=> float(0.049399) 
["pretransfer_time"]=> float(6.5E-5) 
["size_upload"]=> float(0) 
["size_download"]=> float(0) 
["speed_download"]=> float(0) 
["speed_upload"]=> float(0) 
["download_content_length"]=> float(0) 
["upload_content_length"]=> float(0) 
["starttransfer_time"]=> float(0.095534) 
["redirect_time"]=> float(0) 
}

Try this code out.

function get_data($url)
{
    $ch = curl_init();
    $timeout = 15;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt($ch, CURLOPT_USERAGENT, random_user_agent());

    // Edit: Follow redirects
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

    $data = curl_exec($ch);
    var_dump(curl_getinfo($ch));
    curl_close($ch);
    return $data;
}

//Grab HTML
$urllist = fopen("links.txt", "r+");
for ($j = 0; $j <= 50; $j++)
{
    if($post = rtrim(fgets($urllist)))
    {
        echo $post;
        echo get_data($post);
    }
    else
    {
        echo "No URL provided!";
    }

    echo "\n<hr>\n";
}
