PHP - 如何在 class 方法中调用外部名称空间？

Question

I'm using AWS's SDK that requires to use the following namespaces in my code:

use Aws\Ses\SesClient;
use Aws\Exception\AwsException;

I would like to call these namespaces in my class method to look as follows:

class EmailManager {
    public function sendEmail() {
        //new Aws\Ses\SesClient;

        use Aws\Ses\SesClient;
        use Aws\Exception\AwsException;

However, I get the following error when I call the namespaces Parse error: syntax error, unexpected 'use'

This is what I tried so far and worked. However, I want to be able to call it in my method:

use Aws\Ses\SesClient;
use Aws\Exception\AwsException;

class EmailManager {

How can I call this namespaces in my class method?

Thank you

Answer 1

you should insert use outside the Class, and call the imported class by name: SesClient not the full namespace. Or don't put use at all and call by the full namespace every time.

see documentation:

AWS SDK for PHP

Using namespaces: Aliasing/Importing

with use :

require 'vendor/autoload.php';

use Aws\Ses\SesClient; 
use Aws\Exception\AwsException;

class EmailManager {
    public function sendEmail() {
        $SesClient = new SesClient([
            'profile' => 'default',
            'version' => '2010-12-01',
            'region' => 'us-east-2'
        ]);

without use :

class EmailManager {
    public function sendEmail() {
        $SesClient = new \Aws\Ses\SesClient([
            'profile' => 'default',
            'version' => '2010-12-01',
            'region' => 'us-east-2'
        ]);
