Troubles with foreach

[temandroid]

In

foreach ($arr as $ip){
 if (filter_var($ip, FILTER_VALIDATE_IP)) {
  $query=new Query('/queue/simple/print');
  $query->add('?target='.$ip.'/32');
  $responses=$ros->write($query)->read();
  print_r($responses);
  echo "<hr>";
 }

as result have answers like Array ( [after] => Array ( [] => ) )
So new query was exec so fast as I understand...
For now I move $ros=new Client($con); inside foreach and it work, but it's not good, of course, and so slow...

Hello and thanks for your report!
Probably faster solution for right now will be a simple inserting sleep(1); at the end of loop. Something like this:

foreach ($arr as $ip) {
    if (false === filter_var($ip, FILTER_VALIDATE_IP)) {
        continue;
    }

    $query = new Query('/queue/simple/print');
    $query->add('?target=' . $ip . '/32');
    $responses = $ros->write($query)->read();
    print_r($responses);
    echo "<hr>";
    sleep(1);
}

Today (after work) I planned to release a new version of the library. which contains a few of changes that improve the readability of the code. If solution with sleep(1) is will be okay I can add this to new version of library by default.

Hello, thank u for fast reaction :)
It's too slow, if I have more than 100 records in queue with 1s sleep, i tried with usleep(1000000), it work here but also very slow. Is it possible to wait answer from api as end of query?
For now I change logic of my sript for function call one time not 100 times.

Hi @temandroid!

Is it possible to wait answer from api as end of query?

Yep, I think you need to play with 'timeout' parameter of API client, look at this example.

Unfortunately I couldn't reproduce your problem on my router (I've tried to run 100 parallel scripts in same time), maybe you can send me your queue table as an example?

Btw, what is version of RouterOS which you use on your device?

[temandroid]

Hmm, in your example i receiving an array of all queues, not filtered by target...
I make an example on working ROS (6.43.11) this:

$ips=array ();
for ($i=2; $i <= 128; $i++) {
 array_push($ips, '10.50.0.'.$i);
}
$conn=(new Config())->set('timeout', 1)->set('host', '127.0.0.1')->set('user', 'admin')->set('pass', 'admin');
$ros=new Client($conn);
foreach ($ips as $ip) {
 echo $ip."<br>";
 $query=new Query('/queue/simple/print');
 $query->add('?target='.$ip.'/32');
 $response=$ros->write($query)->read();
 print_r($response);
 echo "<hr>";
}

Wow, that's a very strange! Looks like a bug with API socket in RouterOS.
It seems that the socket does not have time to form an answer to your request in time and simply adds each next query one to the query queue.

Probaly just need add yet another call of read method, try this:

$ips=array ();
for ($i=2; $i <= 128; $i++) {
 array_push($ips, '10.50.0.'.$i);
}
$conn=(new Config())->set('timeout', 1)->set('host', '127.0.0.1')->set('user', 'admin')->set('pass', 'admin');
$ros=new Client($conn);
foreach ($ips as $ip) {
 echo $ip."<br>";
 $query=new Query('/queue/simple/print');
 $query->add('?target='.$ip.'/32');
 $response=$ros->write($query)->read();
 print_r($response);
 echo "<hr>";
 // Add this
 $ros->read();
}

I tried, and as a result I was stuck on an IP which is not in the queue...
With class pear2/Net_RouterOS, similar function working well..

 $request=new PEAR2\Net\RouterOS\Request('/queue/simple/print');
 $query=PEAR2\Net\RouterOS\Query::where('target', $ip.'/32');
 $request->setQuery($query);
 $responses=$ros->sendSync($request);
 print_r($responses);

So, I don't think that is a bug

Found it !
You will have a pull request with explanations this evening I hope.

[temandroid]

Sounds good. nice work!
Waiting new release :)

[matracine]

ROS 7 ? ;)

[temandroid]

No)) On release page, like 0.8.2 :)
