php - Having problems adding a timeout to socket_connect() -


i'm sorry if has been asked before. i've looked everywhere can't find solution issue.

i have written socket client function project of mine, , add timeout doesn't take forever load if failed.

i've tried quite few things suggested docs , other answers on stackoverflow, nothing has worked far.

here's function;

    public function send($cmd, $host, $port){          if(!($socket = socket_create(af_inet, sock_stream, sol_tcp)))         {             $errorcode = socket_last_error();             $errormsg = socket_strerror($errorcode);              die("error (#300)");         }          if(!socket_connect($socket, $host, $port))         {             $errorcode = socket_last_error();             $errormsg = socket_strerror($errorcode);              die("error (#400)");         }          if(!socket_write($socket, $cmd, strlen($cmd)))         {             $errorcode = socket_last_error();             $errormsg = socket_strerror($errorcode);              die("error (#301)");         }          $reply = socket_read($socket, 4096)                 or die("error (#302)");          socket_close($socket);         return $reply;     }

i've tried following things;

  • set_time_limit() - doesn't work. takes 20 seconds load shows "maximum execution time of..."
  • ini_set("default_socket_timeout") - still takes 20 seconds load.
  • socket_set_nonblock() - this works, makes socket_connect() fail.
  • https://stackoverflow.com/a/16939666/3457242 - same above. socket_set_nonblock() makes socket_connect() fail.
  • socket_set_option() - takes 20 seconds load. doesn't seem work.

the thing seems work socket_set_nonblock() function, make socket_connect() return false. can't figure out. appreciated.

thanks!

what while loop.

for example:

socket_set_nonblock($socket)     or die("not able set socket nonblock"); $timeout = 5; $starttime = time(); while(!socket_connect($socket, $host, $port)) {     if ((time() - $starttime ) >= $timeout)     {          die('timeout');

you current "socket_last_error" command in while loop. http://www.php.net/manual/en/function.socket-last-error.php

then, before time check if statement, error. if error 114 or 115, should time check error, otherwise can kill instantly error type. example, 100: network down.
