Javascript 如何在PHP中实现ajax？

我需要一些帮助，我有一个jqueryajax函数，我想用PHP来实现它

var accessToken = '237d48b642d5443495a9ec62811c97d7';
       $.ajax({
        type: 'POST',
        url: 'https://api.api.ai/api/query?v=20150910',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        headers: {'Authorization': 'Bearer' + accessToken},
        data: JSON.stringify({query: 'hello u, sessionId: '1'}),
        success: function(data){
          setResponse(data.result.fulfillment.speech);
        }
      });

我想将上述ajax转换为php，我已经完成了以下工作：

$accessToken = '237d48b642d5443495a9ec62811c97d7';
$url = 'https://api.api.ai/api/query?v=20150910';
$data = ['query'=>'stupid', 'sessionId'=>'123'];
$options = array(
  'http' => array(
    'method'  => 'POST',
    'content' => json_encode($data),
    'header'=>  ["Authorization" => "Bearer" . $accessToken "\r\n"] .
                "Content-Type: application/json\r\n"
    )
);

$context  = stream_context_create( $options );
$result = file_get_contents( $url, false, $context );
$response = json_decode( $result );

但我遇到了一个错误，不知道如何解决它

请提供帮助。

尝试切换到PHP CURL：

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,'https://api.api.ai/api/query?v=20150910');
curl_setopt($ch, CURLOPT_POST, 1);

$data = array('query'=>'stupid', 'sessionId'=>'123');
curl_setopt($ch, CURLOPT_POSTFIELDS, 
            http_build_query($data));

$accessToken = '237d48b642d5443495a9ec62811c97d7';
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            'Authorization: Bearer'.$accessToken,
            'Content-Type: application/json'
            ));         

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

$response = json_decode( $server_output );

curl_close ($ch);
