Accelerated file downloads in PHP using Axel

AXEL-PHP - Axel Accelerated Download Functionality For PHP

, _(*1)

General

The AXEL-PHP library wraps around the C based Axel library. Axel performs accelerated downloads from the command line, similar to wget., _(*2)

AXEL-PHP offers asynchronous and synchronous downloads. See below for usage., _(*3)

AXEL-PHP also comes with an optional FIFO download manager with the ability to set numbers of current downloads. Just implement AxelDownloadManagerQueueInterface together with your favourite queuing service., _(*4)

** PLEASE NOTE: This library is under active development as an alpha and is subject to change at any time. **, _(*5)

Example Usages

Sync Download With Complete Callback

$axel = new Axel\AxelDownload();
$axel->start('http://www.google.com', null, null, function($axel, $status, $success, $error) {
    echo 'File Downloaded';
    print_r($status);
});

Start Async Download

$axel = new Axel\AxelDownload();
$axel->startAsync('http://ipv4.download.thinkbroadband.com/1GB.zip', 'test.zip', '~/');

Start Async Download With Progress Callbacks

$axel = new Axel\AxelDownload();
$axel->startAsync('http://ipv4.download.thinkbroadband.com/1GB.zip', 'test.zip', '~/', function($axel, $status, $success, $error) {
   echo 'Progress updated';
   print_r($status);
});

Setup Download / Delayed Start

$axel = new Axel\AxelDownload();
$axel->addDownloadParameters([
    'address'           => 'http://www.google.com',
    'filename'          => 'test.html',
    'download-path'     => '~/',
    'callback'          => function($axel, $status, $success, $error) {
        echo 'Progress updated';
        print_r($status);
    }
]);
$axel->startAsync();

Get Download Status

$status = $axel->updateStatus();

Cleanup

$axel->clearCompleted()

Axel Managed Download Queue (Synchronous)

$dm = new Axel\AxelDownloadManager(new AxelDownloadManagerSyncQueue(), 'axel');
$dm->queueDownload('http://www.google.com', 'file1.html');
$dm->queueDownload('http://www.yahoo.com', 'file2.html');
$dm->processQueue();
