<?php Swoole\Server->getClientList(int $startFd = 0, int $pageSize = 10): bool|array
The starting file descriptor number to begin from as clients connect based on a fd number that increases
How many items are kept per page, the maximum shall not exceed 100
If success, it returns a numeric array based on the starting $fd, otherwise it returns false. The array is sorted from smallest to largest

This method is based shared memory operation, meaning it is fast and does not block, purely asynchronous.
Things to Consider
Server::$connections iterator to traverse these connectionsSWOOLE_BASE mode, only the connection of the current process can obtained<?php
$start_fd = 0;
while(true)
{
$conn_list = $server->getClientList($start_fd, 10);
if($conn_list === false or count($conn_list) === 0)
{
echo "finish\n";
break;
}
$start_fd = end($conn_list);
var_dump($conn_list);
foreach($conn_list as $fd)
{
