workerman常用组件-GlobalData变量共享组件-GlobalDataClient-注意事項

发布时间：2021-12-13 23:19:19编辑：雪饮阅读（）

 注意：

GlobalData组件无法共享资源类型的数据，例如mysql连接、socket连接等无法共享。
如果在Workerman环境中使用GlobalData/Client，请在onXXX回调中实例化GlobalData/Client对象，例如在onWorkerStart中实例化。
不能这样操作共享变量。

<?php
require_once __DIR__ . '/vendor/autoload.php';
class someClass{

}
// 初始化一个全局的global data client
$global = new \GlobalData\Client('127.0.0.1:2207');

$global->somekey = array();
$global->somekey[]='xxx';

$global->someObject = new someClass();
$global->someObject->someVar = 'xxx';

echo "\r\n somekey: \r\n";
var_export($global->somekey);


echo "\r\n someObject: \r\n";
var_export($global->someObject);
?>

我們接著把globalData的服務端先開啓：

[root@localhost www.fpm.com]# /usr/local/php734/bin/php -c /usr/local/php734/lib/php/php.ini server.php start
Workerman[server.php] start in DEBUG mode
-------------------------------------------- WORKERMAN ---------------------------------------------
Workerman version:4.0.22          PHP version:7.3.4
--------------------------------------------- WORKERS ----------------------------------------------
proto   user            worker              listen                    processes    status
tcp     root            globalDataServer    frame://127.0.0.1:2207    1             [OK]
----------------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
然後在命令行測試上面這個客戶端脚本：
[root@localhost www.fpm.com]# /usr/local/php734/bin/php -c /usr/local/php734/lib/php/php.ini start.php
PHP Notice: Indirect modification of overloaded property GlobalData\Client::$somekey has no effect in /www/wwwroot/www.fpm.com/start.php on line 10
 
Notice: Indirect modification of overloaded property GlobalData\Client::$somekey has no effect in /www/wwwroot/www.fpm.com/start.php on line 10
 
 somekey:
array (
)
 someObject:
someClass::__set_state(array(
))
很遺憾就是不給面子呦吼。
但是可以這樣操作：
<?php
require_once __DIR__ . '/vendor/autoload.php';
class someClass{

}
// 初始化一个全局的global data client
$global = new \GlobalData\Client('127.0.0.1:2207');
$somekey = array();
$somekey[] = 'xxx';
$global->somekey=$somekey;

$someObject = new someClass();
$someObject->someVar = 'xxx';
$global->someObject=$someObject;

echo "\r\n somekey: \r\n";
var_export($global->somekey);


echo "\r\n someObject: \r\n";
var_export($global->someObject);
?>

這是沒有問題的

[root@localhost www.fpm.com]# /usr/local/php734/bin/php -c /usr/local/php734/lib/php/php.ini start.php
 
 somekey:
array (
 0 => 'xxx',
)
 someObject:
someClass::__set_state(array(
   'someVar' => 'xxx',
))
