A simple helper function to build GraphQL queries, mutations and subscriptions use PHP.

This project is based on GraphQL Query Builder for Node.js.

Install

composer require mathsgod/gql-query-builder-php

Usage

use function GQLQueryBuilder\query;
use function GQLQueryBuilder\mutation;
use function GQLQueryBuilder\subscription;

$query=query($options);
$mutation=mutation($options);
$subscription=subscription($options);

Options

options is ["operation","field","variables"] or an array of options

Examples

1. Query
2. Query (with variables)
3. Query (with nested fields selection)
4. Query (with custom argument name)
5. Query (with required variables)
6. Query (with empty fields)
7. Mutation
8. Mutation (with required variables)
9. Subscription

Query:

$query=query([
    "operation"=>"thoughts",
    "fields"=>['id', 'name', 'thought']
]);

print_r($query);

// output:
/*
Array
(
    [query] => query { thoughts { id name thought } }
    [variables] => Array
        (
        )
)
*/

Query (with variables):

$query=query([
    "operation"=>"thoughts",
    "fields"=>['id', 'name', 'thought'],
    "variables"=>[
        "id"=>1,
    ]
]);

print_r($query);

// output:
/*
Array
(
    [query] => query ($id: Int) { thoughts(id: $id) { id name thought } }
    [variables] => Array
        (
            [id] => 1
        )
)
*/

Query (with nested fields selection):

$query = query([
    "operation" => "orders",
    "fields" => [
        "id",
        "amount",
        "user" => [
            "id",
            "name",
            "email",
            "address" => [
                "city",
                "country",
            ]
        ]
    ]
]);

// output:
/*
Array
(
    [query] => query { orders { id, amount, user { id, name, email, address { city, country } } } }
    [variables] => Array
        (
        )

)
*/

Query (with custom argument name):

$query = query([
    "operation" => "someoperation",
    "fields" => [
        [
            "operation" => "nestedoperation",
            "fields" => ['field1'],
            "variables" => [
                "id2" => [
                    "name" => "id",
                    "type" => "ID",
                    "value" => 123
                ]
            ],
        ]
    ],
    "variables" => [
        "id" => [
            "name" => "id",
            "type" => "ID",
            "value" => 456
        ]
    ]
]);

/*
Array
(
    [query] => query($id: ID, $id2: ID) { someoperation(id: $id) { nestedoperation (id: $id2)  { field1 }  } }
    [variables] => Array
        (
            [id] => 456
            [id2] => 123
        )
