How to Download a File Using Curl in PHP

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);
?>

Download file from URL using CURL

Give this a go

<?php

    $output_filename = "testfile.igc";

    $host = "http://www.xcontest.org/track.php?t=2avxjsv1.igc";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $host);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_AUTOREFERER, false);
    curl_setopt($ch, CURLOPT_REFERER, "http://www.xcontest.org");
    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    $result = curl_exec($ch);
    curl_close($ch);

    print_r($result); // prints the contents of the collected file before writing..

    // the following lines write the contents to a file in the same directory (provided permissions etc)
    $fp = fopen($output_filename, 'w');
    fwrite($fp, $result);
    fclose($fp);
?>

#

or if you want to put it within a loop for parsing several links... you need some functions.. here is a rough idea....

<?php

    function collect_file($url){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_AUTOREFERER, false);
        curl_setopt($ch, CURLOPT_REFERER, "http://www.xcontest.org");
        curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        $result = curl_exec($ch);
        curl_close($ch);
        return($result);
    }

    function write_to_file($text,$new_filename){
        $fp = fopen($new_filename, 'w');
        fwrite($fp, $text);
        fclose($fp);
    }

    // start loop here

    $new_file_name = "testfile.igc";
    $url = "http://www.xcontest.org/track.php?t=2avxjsv1.igc";

    $temp_file_contents = collect_file($url);
    write_to_file($temp_file_contents,$new_file_name)

    // end loop here
?>

PHP CURL Download File

I solved this problem using this:

curl_setopt($ch, CURLOPT_SSLVERSION,3);

This is the final code:

$source = "https://myapps.gia.edu/ReportCheckPortal/downloadReport.do?reportNo=1152872617&weight=1.35";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
$data = curl_exec ($ch);
$error = curl_error($ch); 
curl_close ($ch);

$destination = "./files/test.pdf";
$file = fopen($destination, "w+");
fputs($file, $data);
fclose($file);

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);

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.

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.
