写一个PHP 采用websocket post请求提交参数：{"orderTitle":"网络质量","processBeginDate":"2023-2-18 1:14:1","processEndDate":"2023-03-20 01:14:01","orderClassStr":null,"flowCode":"","areaId":"13","pageNum":1,"pageSize":20,"gridCode":"synthesizeQueryWo","fuzzy":1}

以下是一个PHP采用websocket post请求提交参数的示例代码：

$url = 'ws://example.com';
$data = '{"orderTitle":"网络质量","processBeginDate":"2023-2-18 1:14:1","processEndDate":"2023-03-20 01:14:01","orderClassStr":null,"flowCode":"","areaId":"13","pageNum":1,"pageSize":20,"gridCode":"synthesizeQueryWo","fuzzy":1}';

$client = new WebSocket\Client($url);
$client->send($data);
$response = $client->receive();

请注意，这里使用了WebSocket客户端库，您需要先安装它。
