AWS PHP使用describeVpcAttribute列出VPC ID

Question

I want to list all VPC Name and VPC ID of my AWS account.

I try with this code but its not working

<?php
 echo "<br><br>VPC<br>";
$vpcs = $ec2Client->describeVpcAttribute();

    foreach ($vpcs as $vpc) {
        $vpcName = '';
        $vpcid = $vpc['VpcId'];
         foreach ($vpc['Tags'] as $tag) {
            if ($tag['Key'] == 'Name') {
                $vpcName = $tag['Value'];
            }
        }
        echo $vpcName . $vpcid .'<br>';
    }
?>

I'm not sure that describeVpcAttribute can list VPC. Can you help me to find the command for this?

Thanks and Regards

Expected: list all VPC Name and VPC ID of my AWS account

Actual results: nothing
