php open 2 tcp socket -


when open 2 different sockets in php, first different resource id, after open next socket, equal resource id. below result of connection 3 different sockets

# ./test.php

127.0.0.1:26379/132458106d92e8f7b 127.0.0.1:26379 - resource id #8 127.0.0.1:6380/320458106d92e906e 127.0.0.1:6380 - resource id #9 127.0.0.1:6381/102858106d92e9106 127.0.0.1:6381 - resource id #10 resource id #10array ( [timed_out] => [blocked] => 1 [eof] => [stream_type] => tcp_socket/ssl [mode] => r+ [unread_bytes] => 0 [seekable] => )

resource id #10array ( [timed_out] => [blocked] => 1 [eof] => [stream_type] => tcp_socket/ssl [mode] => r+ [unread_bytes] => 0 [seekable] => )

resource id #10array ( [timed_out] => [blocked] => 1 [eof] => [stream_type] => tcp_socket/ssl [mode] => r+ [unread_bytes] => 0 [seekable] => )

i'm use below code:

class redisclient     function __construct ($arr = array ())     {         if (count($arr) === 0) return false;          self::$host = $arr[0];         self::$port = $arr[1];         self::$persistent = '/' . uniqid(rand(100,10000));          self::$fp =             stream_socket_client('tcp://'.self::$host . ':' .                                  self::$port .                                  self::$persistent, $errno, $errstr, self::$connect_timeout, self::$flags);          echo self::$host,':',self::$port,self::$persistent,php_eol;          if (!self::$fp) {             echo "$errstr ($errno)" . php_eol;              return false;         }          echo self::$host,':',self::$port,' - ';         print_r(self::$fp);         echo php_eol;          if (!stream_set_timeout(self::$fp, self::$timeout)) return false;      }  function getmeta ()     {         print_r (self::$fp);         print_r (stream_get_meta_data(self::$fp));         return;     }  $c=new redisclient(array('127.0.0.1',26379));  $m=new redisclient(array('127.0.0.1',6380));  $s=new redisclient(array('127.0.0.1',6381));  $c->getmeta(); echo php_eol; $m->getmeta(); echo php_eol; $s->getmeta(); echo php_eol;  exit;

anybody know, why after sockets connected, resource id, indentical? , how make different ?

you used self::$fp (static variable), need use $this in class different variable object.

"self::$var = 1;" - create 1 variable class (without object)

"$this->var = 1;" - create attribute in object

for example can write:

class test {    protected $a = 1;    protected static $b = 1;    public function inca()    {        $this->a++;    }    public static function incb()    {        self::$b++;    }    public function geta()    {        return $this->a;    }    public static function getb()    {        return self::$b;    } } $test = new test(); $test->inca(); $test->inca(); var_dump($test->geta()); var_dump(test::getb()); // or $test::getb();  test::incb(); $test2 = new test(); var_dump($test2->geta()); var_dump($test2::getb()); var_dump($test::getb()); var_dump(test::getb());

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
