Download File to server from URL
PhpHttpStreamDownloadPhp Problem Overview
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.
Php Solutions
Solution 1 - Php
Since PHP 5.1.0, file_put_contents() supports writing piece-by-piece by passing a stream-handle as the $data parameter:
file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));
From the manual:
> If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using
> stream_copy_to_stream().
(Thanks Hakre.)
Solution 2 - Php
private function downloadFile($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);
}
}

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($ch);
I'm not sure but I believe with the CURLOPT_FILE option it writes as it pulls the data, ie. not buffered.
Solution 4 - Php
prodigitalson's answer didn't work for me. I got missing fopen in CURLOPT_FILE more details.
This worked for me, including local urls:
function downloadUrlToFile($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 $httpcode;
}
}
Solution 5 - Php
- Create a folder called "downloads" in destination server
- Save [this code] into
.phpfile and run in destination server
Downloader :
<html>
<form method="post">
<input name="url" size="50" />
<input name="submit" type="submit" />
</form>
<?php
// maximum execution time in seconds
set_time_limit (24 * 60 * 60);
if (!isset($_POST['submit'])) die();
// folder to save downloaded files to. must end with slash
$destination_folder = 'downloads/';
$url = $_POST['url'];
$newfname = $destination_folder . basename($url);
$file = fopen ($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);
}
?>
</html>
Solution 6 - Php
set_time_limit(0);
$file = file_get_contents('path of your file');
file_put_contents('file.ext', $file);
Solution 7 - Php
Use a simple method in php copy()
copy($source_url, $local_path_with_file_name);
Note: if the destination file already exists, it will be overwritten
Note: You need to set permission 777 for the destination folder. Use this method when you are downloading to your local machine.
Special Note: 777 is a permission in Unix based system with full read/write/execute permission to owner, group and everyone. In general we give this permission to assets which are not much needed to be hidden from public on a web server. Example: images folder.
Solution 8 - Php
There are 3 ways:
- file_get_contents and file_put_contents
- CURL
- fopen
You can find examples from here.

Solution 10 - Php
A PHP 4 & 5 Solution:
readfile() will not present any memory issues, even when sending large files, on its own. A URL can be used as a filename with this function if the fopen wrappers have been enabled.

Simple solution:
<?php
exec('wget http://someurl/file.zip');
