編譯php時指定php.ini位置

在compile php時，可以透過--with-config-file-path 參數來指定位置，可以從原始碼複製php.ini 通常有兩個選擇 一個是開發階段的參數 一個則是生產階段的參數

getConstants

php中反射（ReflectionClass）的語法


如果想要取得物件中取得const的陣列可以使用



    const STATE0 = 'open';
    const STATE1 = 'close';
    const STATE2 = 'run1';
    const STATE3 = 'run2';
    const STATE4 = 'run3';
   
    static function getConstants() {
        $oClass = new ReflectionClass(__CLASS__);
        return $oClass->getConstants();
    }

Zend Framework多資料庫設定

因為在ZF中資料庫是以資源的方式提供
所以在application.ini中設置

[production]

resources.multidb.db1.adapter = "pdo_mysql"

resources.multidb.db1.host = "localhost"

resources.multidb.db1.username = "webuser"

resources.multidb.db1.password = "XXXX"

resources.multidb.db1.dbname = "db1"

resources.multidb.db2.adapter = "pdo_pgsql"

resources.multidb.db2.host = "example.com"

resources.multidb.db2.username = "dba"

resources.multidb.db2.password = "notthatpublic"

resources.multidb.db2.dbname = "db2"

resources.multidb.db2.default = true

再由Bootstrap取得資料庫

$resource = $bootstrap->getPluginResource('multidb');

$db1 = $resource->getDb('db1');

$db2 = $resource->getDb('db2');

$defaultDb = $resource->getDb();

ZendFramework的bootstrap

在ZendFramework的bootstrap中，如果方法名稱以_init為前綴，將被當成資源方法
來自動執行，如果你手上有現成的資源插件(Pluging)，可以透過前導的方法 將該資源
排定執行 但該注意的是 當你是使用module模式時 所有module下的bootstrap將會全部
執行 造成 資源重載  效能低下 後來是以取得該module name為判斷 當非執行該module就return 不繼續執行執行非該module的pluging

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap

{

    protected function _initView()

    {

        $view = new Zend_View();

        // more initialization...

        return $view;

    }

}

class FooController extends Zend_Controller_Action

{

    public function init()

    {

        $bootstrap = $this->getInvokeArg('bootstrap');

        $view = $bootstrap->getResource('view');

        // ...

    }

}

Linux Pipe小工具

Linux sort的常用
