Is the GraphQL Admin documentation for PHP correct? Getting syntax errors

[chrisan]

Hello, first time using shopify (and GraphQL for that matter).  We are looking to create a subscription for our app but the PHP code to initiate this is giving errors: https://shopify.dev/docs/api/admin-graphql/2024-04/mutations/appSubscriptionCreate#examples-Create_a...

use Shopify\Clients\Graphql;

$client = new Graphql("your-development-store.myshopify.com", $accessToken);
$query = <<<QUERY
mutation AppSubscriptionCreate($name: String!, $lineItems: [AppSubscriptionLineItemInput!]!, $returnUrl: URL!, $trialDays: Int) {
appSubscriptionCreate(name: $name, returnUrl: $returnUrl, lineItems: $lineItems, trialDays: $trialDays) {
userErrors {
field
message
}
appSubscription {
id
}
confirmationUrl
}
}
QUERY;

$variables = [
"name" => "Super Duper Recurring Plan with a Trial",
"returnUrl" => "http://super-duper.shopifyapps.com/",
"trialDays" => 7,
"lineItems" => [{"plan"=>{"appRecurringPricingDetails"=>{"price"=>{"amount"=>10.0, "currencyCode"=>"USD"}}}}],
];

$response = $client->query(["query" => $query, "variables" => $variables]);

 "Parse error: syntax error, unexpected token "{", expecting "]""

If I change the $variables to the following to match what I know as PHP's style:

$variables = [
"name" => "Super Duper Recurring Plan with a Trial",
 "returnUrl" => "http://super-duper.shopifyapps.com/",
 "trialDays" => 7,
 "lineItems" => ["plan"=> [
"appRecurringPricingDetails"=> [
"price"=>["amount"=>10.0, "currencyCode"=>"USD"]
]
]
]];

I now get undefined variables for $name etc, but my understanding of GraphQL is getting in the way.

Can anyone provide a working example? Running PHP 8.3

OK worked out all the errors, for anyone who runs into this in the future and if shopify doesn't update their docs

   $client = new Graphql("your-development-store.myshopify.com", $accessToken);
    $query = <<<QUERY
  mutation AppSubscriptionCreate(\$name: String!, \$lineItems: [AppSubscriptionLineItemInput!]!, \$returnUrl: URL!, \$trialDays: Int) {
    appSubscriptionCreate(name: \$name, returnUrl: \$returnUrl, lineItems: \$lineItems, trialDays: \$trialDays) {
      userErrors {
        field
        message
      }
      appSubscription {
        id
      }
      confirmationUrl
    }
  }
QUERY;

    $variables = [
      "name" => "Super Duper Recurring Plan with a Trial",
      "returnUrl" => "http://super-duper.shopifyapps.com/",
      "trialDays" => 7,
      "lineItems" => ["plan"=> [
        "appRecurringPricingDetails"=> [
          "price"=>["amount"=>10.0, "currencyCode"=>"USD"]
          ]
        ]
        ]];


$response = $client->query(["query" => $query, "variables" => $variables]);
