写一个PHP 采用socket 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socket post请求提交参数的示例代码：

<?php
// 设置请求参数
$params = array(
    '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
);

// 将参数转换为字符串
$data = http_build_query($params);

// 设置请求头
$header = "POST /path/to/api HTTP/1.1\r\n";
$header .= "Host: example.com\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($data) . "\r\n";
$header .= "Connection: close\r\n\r\n";

// 发送请求
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, 'example.com', 80);
socket_write($socket, $header . $data);
$response = '';

// 读取响应
while ($buffer = socket_read($socket, 1024)) {
    $response .= $buffer;
}

// 关闭连接
socket_close($socket);

// 输出响应
echo $response;
?>

请注意，您需要将上面的代码中的“/path/to/api”和“example.com”替换为实际的API路径和主机名。此外，您还需要根据实际情况更改请求头中的其他字段。
