How to get the mime type of a file after using file_get_contents from a remote server

Use cURL instead of file_get_contents, then you can see the response header, which will hopefully have the mime type.

Or you could try using this http://www.php.net/manual/en/ref.fileinfo.php or this deprecated function http://php.net/manual/en/function.mime-content-type.php

Download external file with PHP fopen and/or cURL

You can try this process as well, I am assuming that your source url is $sourceUrl and destination/ path to save file is $destinationPath

$destFilename = 'my_file_name.ext';
$destinationPath = 'your/destination/path/'.$destFilename;

if(ini_get('allow_url_fopen')) {                                
    if( ! @file_put_contents($destinationPath, file_get_contents($sourceUrl))){
        $http_status = $http_response_header[0];
        sprintf('%s encountered while attempting to download %s',$http_status, $sourceUrl );
        break;
    }
} elseif(function_exists('curl_init')) {
    $ch = curl_init($sourceUrl);
    $fp = fopen($destinationPath, "wb");

    $options = array(
        CURLOPT_FILE => $fp,
        CURLOPT_HEADER => 0,
        CURLOPT_FOLLOWLOCATION => 1,
        CURLOPT_TIMEOUT => 120); // in seconds

    curl_setopt_array($ch, $options);
    curl_exec($ch);
    $http_status = intval(curl_getinfo($ch, CURLINFO_HTTP_CODE));
    curl_close($ch);
    fclose($fp);

    //delete the file if the download was unsuccessful
    if($http_status != 200) {
        unlink($destinationPath);
        sprintf('HTTP status %s encountered while attempting to download %s', $http_status, $sourceUrl );

    }
} else {    
    sprintf('Looks like %s is off and %s is not enabled. No images were imported.', '<code>allow_url_fopen</code>', '<code>cURL</code>'  );
    break;
}

You can use curl_getinfo($ch, CURLINFO_CONTENT_TYPE); in case of curl to get the file info and use it as per your requirement.

php/curl - get extension of image on remote server using headers

solution

$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_exec ($ch);

$content_type = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
echo $content_type;

Send file via cURL from form POST in PHP

Here is some production code that sends the file to an ftp (may be a good solution for you):

// This is the entire file that was uploaded to a temp location.
$localFile = $_FILES[$fileKey]['tmp_name']; 

$fp = fopen($localFile, 'r');

// Connecting to website.
$ch = curl_init();

curl_setopt($ch, CURLOPT_USERPWD, "email@email.org:password");
curl_setopt($ch, CURLOPT_URL, 'ftp://@ftp.website.net/audio/' . $strFileName);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'CURL_callback');
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
curl_exec ($ch);

if (curl_errno($ch)) {

    $msg = curl_error($ch);
}
else {

    $msg = 'File uploaded successfully.';
}

curl_close ($ch);

$return = array('msg' => $msg);

echo json_encode($return);
