Problems with the result Curl and file_get_contents

Question

I’m trying to get an image from a website to use imagecreatefrompng(), but the backlash was never what I expected...

Url: https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m in the case when I call as <img> works perfectly

<img src="https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m">

the problem is that when I call Curl returns it:

already tried to use file_get_contents but it’s a https url and it doesn’t work, I want you to return the image to use with imagecreatefrompng() from php

code I used:

function getimg($url) {
    $headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';
    $headers[] = 'Connection: Keep-Alive';
    $headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';

    $process = curl_init($url);

    curl_setopt($process, CURLOPT_URL, $url);
    curl_setopt($process, CURLOPT_HEADER, false);
    curl_setopt($process, CURLOPT_HTTPHEADER, array('Accept-Encoding: gzip, deflate, sdch'));
    curl_setopt($process, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($process, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($process, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($process, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($process, CURLOPT_SSL_VERIFYPEER, 0);

    $return = curl_exec($process);
    curl_close($process);

    return $return;
}

echo getimg('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m');

//echo '<img src="'.getimg('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m').'">';
//$habbo = imagecreatefrompng('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m');
//imagecopy($im, $habbo, -2, -9, 0, 0, 33, 33);

I just tested here successfully:

It can actually be simpler than what you were doing:

function getimg($url) {
    $process = curl_init();
    curl_setopt($process, CURLOPT_URL, $url);
    curl_setopt($process, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($process, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    $return = curl_exec($process);
    curl_close($process) ;
    return $return;
}

header("Content-Type: image/jpeg");
echo getimg('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m');

Here a solution with file_get_contents():

function getimg($url) {
    $options = array(
        'http'=>array(
            'method'=> "GET",
            'header'=> "Accept-language: en\r\n" .
            'User-Agent: ' .$_SERVER['HTTP_USER_AGENT']. "\r\n"
        )
    );
    $context = stream_context_create($options);
    return file_get_contents($url, false, $context);
}
header("Content-Type: image/jpeg");
echo getimg('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m');

You can use the following code, which makes use of the file_get_contents instead of curl, in it is passed the User-Agent so that the connection is not rejected, the capture of the mime-type automatically via the function finfo.

To avoid errors in obtaining the mime-type, check on php.ini if the dll of fileinfo is enabled extension=php_fileinfo.dll without the ;.

function getimg($url) {
$options = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"User-Agent: Mozilla/5.0 (Android; Mobile; rv:40.0) Gecko/40.0 Firefox/40.0
\r\n" // Edite com o user agent que você deseja usar
  )
);

$context = stream_context_create($options);
$image = file_get_contents($url, false, $context);

//Obtem o Mime Type
$file_info = new finfo(FILEINFO_MIME_TYPE);
$mime_type = $file_info->buffer($image);

return 'data:'.$mime_type.';base64,'.base64_encode($image);
} 

echo '<img src="'.getimg('https://www.habbo.com.br/habbo-imaging/avatarimage?user=vfr&direction=3&size=m').'">';

With this you can make use of the <img src= to use the images directly in the code without the need to use the header.
