Curl - slow response

I got the address and port number from someone. I send something called a "tag" and get the answer back, zpl tag.

I have to start Uni-Box by sending this tag tag through a socket connection. I tried to do this with curl. It works, but it takes about 10 seconds before I get a response.

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, '87.213.39.202'); curl_setopt($ch, CURLOPT_PORT, 3032); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch, CURLOPT_POSTFIELDS, $message); $zpl = curl_exec($ch); curl_close($ch); 

This is what I get from curl_getinfo ():

 array:26 [▼ "url" => "HTTP://87.213.39.202/" "content_type" => null "http_code" => 0 "header_size" => 0 "request_size" => 538 "filetime" => -1 "ssl_verify_result" => 0 "redirect_count" => 0 "total_time" => 10.327 "namelookup_time" => 0.0 "connect_time" => 0.031 "pretransfer_time" => 0.031 "size_upload" => 410.0 "size_download" => 8598.0 "speed_download" => 832.0 "speed_upload" => 39.0 "download_content_length" => -1.0 "upload_content_length" => 410.0 "starttransfer_time" => 0.062 "redirect_time" => 0.0 "redirect_url" => "" "primary_ip" => "87.213.39.202" "certinfo" => [] "primary_port" => 3032 "local_ip" => "192.168.1.136" "local_port" => 49948 ] 

I also checked the connection through this program: http://sockettest.sourceforge.net/

When I use this, I get a response right away.

I made a trace with xdebug:

I found something that works, but not sure if this is the best way.

Do not use curl this time. If I use socket_read when there is nothing to read, it takes another 10 seconds to get the result. But I know the characters that should receive received messages, so I use this to determine when to stop.

It works, and it takes less time!

 $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); $result = socket_connect($socket, '87.213.39.202', 3032); socket_write($socket, $message, strlen($message)); $result = ''; $zpl = ''; for($i = 0; $i < 10; $i++) { $read = socket_read($socket, 2048); $zpl = $zpl . $read; if(substr($read, -13) == '/////GLS/////') { break; } } socket_close($socket);

  • HTTP is not the same as HTTP
  • "http_code" => 0 - this means that an error occurred during the request and it was not even completed.
