Strange behavior when receiving multiple tcp messages at the time

[LAGGOUNE-Walid]

Hello everyone, i am using a simple swoole TCP server. And this is my php tcp client code :

$i = 0;
$start = microtime(true);
while($i <= 100) {
    socket_write($sock, "hi");
    $i++;
}
echo "Seneded ".$i." \n";
socket_close($sock);

On my server side

$server->on('Receive', function ($server, $fd, $fromId, $data) use ($self) {
   echo "Data: ".$data."\n";
});

i thought that the server will print the data like this

Data: hi
Data: hi
Data: hi
...

But the server printed the data like this:

Data: hihihihihihihihihihihihihihihihihi
Data: hihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihihi
Data: hihihihihihihihihihihihi
Data: hihihihihihihi
Data: hihihihihihihi
Data: hihihihihihihi
Data: hihihihihihihi
Data: hihihihihihihi

What can i do to solve this ?
