Re: [請益] 物件中的物件表示法
: //factory setting
: //這邊有用到JAVA的雙重鎖定檢查
: //另外還加了synchronized的方式(不過不知道php有沒有效減少資源)
: public static function getInstance()
: {
: if (self::$instance === NULL)
: {
: //TODO sem muilt process set
: $SEMKey = "99999";
: //TODO sem muilt process start
: sem_acquire($seg);
: if (self::$instance === NULL)
: {
: self::$instance = new self;
: }
: sem_release($seg);
: }
: return self::$instance;
: }
這…
singleton / factory 是很好用沒錯，
但是這個 instance resource 除非是可共用的競爭性 resource ，
不然抓到 semaphore 去跑好像有點… XDD
