php-awsHow do I use the PHP AWS SDK to invoke a Lambda function?

Using the PHP AWS SDK to invoke a Lambda function is a straightforward process.

First, you'll need to install the AWS SDK using composer:

composer require aws/aws-sdk-php

Then, create a new Aws\Lambda\LambdaClient object with your AWS credentials and the desired region:

$client = new Aws\Lambda\LambdaClient([
    'version' => 'latest',
    'region'  => 'us-east-1',
    'credentials' => [
        'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
        'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
    ]
]);

Finally, use the invoke() method to invoke the Lambda function. You'll need to provide the name of the function, as well as the JSON-encoded input data:

$result = $client->invoke([
    'FunctionName' => 'myFunction',
    'Payload' => '{"foo":"bar"}'
]);

The invoke() method will return a Promise object. To get the result of the Lambda function, you can call the get() method:

$result = $result->get();

The result will be a Aws\Result object, which contains the output and other information about the invocation.
