S3 Batch / Parallel Upload Error with PHP SDK

Question

I followed these codes to batch PutObject into S3. I am using the latest PHP SDK (3.x). But I am getting:

Argument 1 passed to Aws\AwsClient::execute() must implement interface Aws\CommandInterface, array given

$commands = array();
$commands[] = $s3->getCommand('PutObject', array(
    'Bucket' => $bucket,
    'Key'    => 'images/1.jpg',
    'Body' => base64_decode( 'xxx' ),
    'ACL' => 'public-read',
    'ContentType' => 'image/jpeg'
));

$commands[] = $s3->getCommand('PutObject', array(
    'Bucket' => $bucket,
    'Key'    => 'images/2.jpg',
    'Body' => base64_decode( 'xxx' ),
    'ACL' => 'public-read',
    'ContentType' => 'image/jpeg'
));

// Execute the commands in parallel
$s3->execute($commands);

If you're using a modern version of the SDK, try building the command this way, instead. Taken straight from the docs; it should work. This is called the "chaining" method.

$commands = array();


$commands[] = $s3->getCommand('PutObject')
                ->set('Bucket', $bucket)
                ->set('Key', 'images/1.jpg')
                ->set('Body', base64_decode('xxx'))
                ->set('ACL', 'public-read')
                ->set('ContentType', 'image/jpeg');

$commands[] = $s3->getCommand('PutObject')
                ->set('Bucket', $bucket)
                ->set('Key', 'images/2.jpg')
                ->set('Body', base64_decode('xxx'))
                ->set('ACL', 'public-read')
                ->set('ContentType', 'image/jpeg');

// Execute the commands in parallel
$s3->execute($commands);

// Loop over the commands, which have now all been executed
foreach ($commands as $command)
{
    $result = $command->getResult();

    // Use the result.
}

Make sure you're using the latest version of the SDK.

Edit

It appears that the SDK's API has changed significantly in Version 3.x. The above example should work correctly in Version 2.x of the AWS SDK. For 3.x, you need to use CommandPool()s and promise():

$commands = array();

$commands[] = $s3->getCommand('PutObject', array(
    'Bucket' => $bucket,
    'Key'    => 'images/1.jpg',
    'Body' => base64_decode ( 'xxx' ),
    'ACL' => 'public-read',
    'ContentType' => 'image/jpeg'
));
$commands[] = $s3->getCommand('PutObject', array(
    'Bucket' => $bucket,
    'Key'    => 'images/2.jpg',
    'Body' => base64_decode ( 'xxx' ),
    'ACL' => 'public-read',
    'ContentType' => 'image/jpeg'
));


$pool = new CommandPool($s3, $commands);

// Initiate the pool transfers
$promise = $pool->promise();

// Force the pool to complete synchronously
try {
    $result = $promise->wait();
} catch (AwsException $e) {
    // handle the error.
}

Then, $result should be an array of command results.

Isn't this the same as I have coded? The error is failing at $s3->execute($commands); – twb Jul 10 '15 at 07:49
The difference is the `->set()` chaining rather than the `array()` of parameters. What version are you using? – Will Jul 10 '15 at 07:50
Didn't work. Using ## 3.0.4 - 2015-06-11. Call to undefined method Aws\Command::set() – twb Jul 10 '15 at 08:08
I just added a new example for AWS SDK 3.x. They've made significant changes. Let me know if this works for you. – Will Jul 10 '15 at 08:25
The example will still fail at ->set('Bucket', $bucket)?? – twb Jul 10 '15 at 08:31
Sorry, an oversight on my part. Fixed! – Will Jul 10 '15 at 08:34
Sweet! How shall I get the ObjectURL for each object? – twb Jul 10 '15 at 08:39
I don't have an environment with the 3.0 SDK set up to test with, but, I believe $result will be an array of result arrays, so, something like `$result[0]['ObjectURL']` for the first one, and so on. Maybe `var_dump()` out `$result` to see what it contains, as I'm not totally sure about this part. – Will Jul 10 '15 at 08:41
var_dump($result); shows NULL. will try to google :) – twb Jul 10 '15 at 08:51
What happens if you change `$promise->wait()` to `$promise->wait(true)`? – Will Jul 10 '15 at 08:54
