|
<p>Query execution is a complex process involving multiple steps, including query <strong>parsing</strong>,
|
|
<strong>validating</strong> and finally <strong>executing</strong> against your <a href="../type-system/schema/">schema</a>.</p>
|
|
<p><strong>graphql-php</strong> provides convenient facade for this process in class <code>GraphQL\GraphQL</code>:</p>
|
|
<pre><code class="php">use GraphQL\GraphQL;
|
|
|
|
$result = GraphQL::execute(
|
|
$schema,
|
|
$queryString,
|
|
$rootValue = null,
|
|
$contextValue = null,
|
|
$variableValues = null,
|
|
$operationName = null
|
|
);
|
|
</code></pre>
|
|
|
|
<p>Method returns <code>array</code> with <strong>data</strong> and <strong>errors</strong> keys, as described by
|
|
<a href="http://facebook.github.io/graphql/#sec-Response-Format">GraphQL specs</a>.
|
|
This array is suitable for further serialization (e.g. using <code>json_encode</code>).
|
|
See also section on <a href="../error-handling/">error handling</a>.</p>

|
