download a file from PHP Curl - php

Question

I have this code in my curl:
$data_string = json_encode($data);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json; charset=utf-8',
'User-Agent: '.$_SERVER['HTTP_USER_AGENT'],
'X-Forwarded-For: '.$this->getIp()
));
$result = curl_exec($ch);
return $result;
I am getting this giberish result:
I am expecting an image file.
Question here is that how can i download this image file?

Answer 1

you can use this code
$profile_Image = $url; //image url
$userImage = 'myimg.jpg'; // renaming image
$path = ''; // your saving path
$ch = curl_init($profile_Image);
$fp = fopen($path . $userImage, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
curl_close($ch);
fclose($fp);

Answer 2

you can try this:
$data=send_curl($url);
$path='./test.jpg';
$file = file_put_contents($path,$data);
the function of send_curl
function send_curl($url, $data, $PROXY = "") {
$ch = curl_init ();
if ($PROXY != "") {
curl_setopt ( $ch, CURLOPT_PROXY, $PROXY );
}
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$result = curl_exec ( $ch );
curl_close ( $ch );
return $result;
}

Ideally, browsers decide how to display a given piece of content using the information of the Content-Type HTTP header and PHP can generate HTTP headers with the header() function.
If you know for sure that your picture will always be in JPEG format it's rather straightforward:
header('Content-Type: image/jpeg');
echo your_download_function();
exit;
Otherwise, you need to fetch the header returned by the remote server. Curl has a tricky syntax—I refer you to PHP cURL retrieving response headers AND body in a single request?
