You need to get Ec2Client instance first. The easiest way to initialize the client:

First get the EC2Client instance, then initialize the client using this:

$config = array();

$config['key'] = 'key';

$config['secret'] = 'secret';

$config['region'] = 'us-east-1';

$config['version'] = 'latest'; // Or Specified

$ec2Client = \Aws\Ec2\Ec2Client::factory($config);

Then call DescribeInstances method.

$result = $ec2Client->DescribeInstances(array(

        'Filters' => array(

                array('Name' => 'instance-type', 'Values' => array('m1.small')),

        )

));
 

You can get a list of available filters on the Amazon DescribeInstances API method page.

But there will be problems during the API call because Filters here is Filter in the API. And also Values here is called different where it is an Array. So, there need to be a few updates which could be hard to choose.

Check out this example which could print out the output.

$reservations = $result['Reservations'];

foreach ($reservations as $reservation) {

    $instances = $reservation['Instances'];

    foreach ($instances as $instance) {

        $instanceName = '';

        foreach ($instance['Tags'] as $tag) {

            if ($tag['Key'] == 'Name') {

                $instanceName = $tag['Value'];

            }

        }


 

        echo 'Instance Name: ' . $instanceName . PHP_EOL;

        echo '---> State: ' . $instance['State']['Name'] . PHP_EOL;

        echo '---> Instance ID: ' . $instance['InstanceId'] . PHP_EOL;

        echo '---> Image ID: ' . $instance['ImageId'] . PHP_EOL;

        echo '---> Private Dns Name: ' . $instance['PrivateDnsName'] . PHP_EOL;

        echo '---> Instance Type: ' . $instance['InstanceType'] . PHP_EOL;

        echo '---> Security Group: ' . $instance['SecurityGroups'][0]['GroupName'] . PHP_EOL;

    }

}
