Saving File Using Curl and PHP

How to download and save a file to local path using CURL

Ok, got the solution. Sharing my answer.

$getFile = 'http://url to file/file.csv';
$getParams  = array ();

$path = '/var/save/to/local/path/file_name.csv';
$fp = fopen($path, 'w');
$ch = curl_init($getFile);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies');
$data = curl_exec($ch);

if(fwrite($fp,$data))
{
    return true;
}
else
{
    return false;
}

Thanks all for your help.

Save image from url with curl PHP

try this:

function grab_image($url,$saveto){
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($saveto)){
        unlink($saveto);
    }
    $fp = fopen($saveto,'x');
    fwrite($fp, $raw);
    fclose($fp);
}

and ensure that in php.ini allow_url_fopen is enable

Using cURL to save external files to my Server

$local_file = "/tmp/filename.flv";//This is the file where we save the information
$remote_file = "http://www.test.com/filename.flv"; //Here is the file we are downloading

$ch = curl_init();
$fp = fopen ($local_file, 'w+');
$ch = curl_init($remote_file);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_ENCODING, "");
curl_exec($ch);
curl_close($ch);
fclose($fp);

I've decided to update this answer almost 7 years later.

For those who have copy() enabled for remote hosts, you can simply use:

copy("http://www.test.com/filename.flv", "/some/local/path/filename.flv");

Downloading Files with PHP and CURL

with the CURLOPT_RETURNTRANSFER option is set curl_exec will return downloaded content in the result. So, your variable $result actually contains the content of the file (PKr�... is a ZIP-header)

So, all you need, just to save the content of the variable in a file, instead of echoing it into the browser.

For example.

    ...

    $result = curl_exec($ch);

    file_put_contents('downloaded.zip', $result); // save the string to a file

    curl_close ($ch);

php curl to download files

If i interpret this correct you want to build something like a cache where you download file x once from a remote server and after that the file should be served from your own server ?

If that is the case this could be a good approach for the problem:

class Downloader
{

    private $path;
    public $filename;

    public function __construct()
    {
        $this->path = dirname(__FILE__);
    }

    public function getFile($url)
    {
        $fileName = $this->getFileName($url);
        if(!file_exists($this->path."/".$fileName)){
            $this->downloadFile($url,$fileName);
        }

        return file_get_contents($this->path."/".$fileName);
    }

    public function getFileName($url)
    {
        $slugs = explode("/", $url);
        $this->filename = $slugs[count($slugs)-1];
        return $this->filename;
    }

    private function downloadFile($url,$fileName)
    {
        //This is the file where we save the information
        $fp = fopen ($this->path.'/'.$fileName, 'w+');
        //Here is the file we are downloading, replace spaces with %20
        $ch = curl_init(str_replace(" ","%20",$url));
        curl_setopt($ch, CURLOPT_TIMEOUT, 50);
        // write curl response to file
        curl_setopt($ch, CURLOPT_FILE, $fp); 
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        // get curl response
        curl_exec($ch); 
        curl_close($ch);
        fclose($fp);
    }

}

$downloader = new Downloader();
$content = $downloader->getFile("YOUR URL");

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$downloader->filename.'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . mb_strlen($content));
print $content;
exit;

This is a very basic concept there are many point this have to be improved and customized for your use case.

Downloading a large file using curl

<?php
set_time_limit(0);
//This is the file where we save the    information
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
// make sure to set timeout to a high enough value
// if this is too low the download will be interrupted
curl_setopt($ch, CURLOPT_TIMEOUT, 600);
// write curl response to file
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// get curl response
curl_exec($ch); 
curl_close($ch);
fclose($fp);
?>

php curl not saving file to location

OK, finally got it all working and here is the code if anyone else ever tries to do the same sort of thing!

I was missing these parts:

    $dir = $_SERVER['DOCUMENT_ROOT'] . "/img/products/";

and

    fwrite($file,$contents);

So here is my final code... credit to Sébastien for pointing me in the right direction. Thanks.

        if($method == 'save')
        {
            $productId = Input::get('pId');
            $removeProductImages = DB::table('product_ref_images')->where('product_id', '=', $productId)->delete();

            $imagesData = Input::get('imageRefs');

            $dir = $_SERVER['DOCUMENT_ROOT'] . "/img/products/";

            $sortOrder = 0;

            for ($i=0; $i < count($imagesData); $i++) {

                $imgSrc = trim($imagesData[$i]['imgSrc']);
                $imgId = trim($imagesData[$i]['imgId']);

                $file = fopen($dir . basename($imgSrc), "wb");

                $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';         
                $user_agent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)';  

                $ch = curl_init($imgSrc);
                curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);         
                curl_setopt($ch, CURLOPT_HEADER, 0);         
                curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                curl_setopt($ch, CURLOPT_FILE, $file);
                curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
                $contents = curl_exec($ch);
                $curl_errno = curl_errno($ch);
                $curl_error = curl_error($ch);
                curl_close($ch);

                if ($curl_errno > 0) 
                {
                    Log::write("CURL", "cURL Error (".$curl_errno."): ".$curl_error);
                    break;
                } 
                else 
                {
                    fwrite($file,$contents);
                    fclose($file);

                    $imageIds = DB::table('product_ref_images')->order_by('image_id', 'desc')->first();

                    if($imageIds == null)
                    {
                        $imageIds = 0;
                    }
                    else
                    {
                        $imageIds = $imageIds->image_id;
                    }

                    $updateImages = DB::table('product_ref_images')
                        ->insert(array(
                            'image_id'          =>  $imageIds + 1,
                            'product_id'        =>  $productId,
                            'flickr_image_id'   =>  $imgId,
                            'sort_order'        =>  $sortOrder++,
                            'local_storage_url' =>  $dir . basename($imgSrc),
                            'created_at'        =>  date("Y-m-d H:i:s"),
                            'updated_at'        =>  date("Y-m-d H:i:s")
                    ));
                }
            }
            return Response::json('Complete');
        }
