Download File to server from URL
Well, this one seems quite simple, and it is. All you have to do to download a file to your server is:
file_put_contents("Tmpfile.zip", file_get_contents("http://someurl/file.zip"));
Only there is one problem. What if you have a large file, like 100mb. Then, you will run out of memory, and not be able to download the file.
What I want is a way to write the file to the disk as I am downloading it. That way, I can download bigger files, without running into memory problems.
Solution 1:
Since PHP 5.1.0, file_put_contents()
supports writing piece-by-piece by passing a stream-handle as the $data
parameter:
file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));
From the manual:
If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using
stream_copy_to_stream()
.
(Thanks Hakre.)
Solution 2:
private function downloadFile($url, $path)
{
$newfname = $path;
$file = fopen ($url, 'rb');
if ($file) {
$newf = fopen ($newfname, 'wb');
if ($newf) {
while(!feof($file)) {
fwrite($newf, fread($file, 1024 * 8), 1024 * 8);
}
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
}
}
Solution 3:
Try using cURL
set_time_limit(0); // unlimited max execution time
$options = array(
CURLOPT_FILE => '/path/to/download/the/file/to.zip',
CURLOPT_TIMEOUT => 28800, // set this to 8 hours so we dont timeout on big files
CURLOPT_URL => 'http://remoteserver.com/path/to/big/file.zip',
);
$ch = curl_init();
curl_setopt_array($ch, $options);
curl_exec($ch);
curl_close($ch);
I'm not sure but I believe with the CURLOPT_FILE
option it writes as it pulls the data, ie. not buffered.
Solution 4:
prodigitalson's answer didn't work for me. I got missing fopen in CURLOPT_FILE
more details.
This worked for me, including local urls:
function downloadUrlToFile($url, $outFileName)
{
if(is_file($url)) {
copy($url, $outFileName);
} else {
$options = array(
CURLOPT_FILE => fopen($outFileName, 'w'),
CURLOPT_TIMEOUT => 28800, // set this to 8 hours so we dont timeout on big files
CURLOPT_URL => $url
);
$ch = curl_init();
curl_setopt_array($ch, $options);
curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return $httpcode;
}
}
