pdo 中文意思是什麼

pdo 解釋
阿曼石油開發公司
  1. Now that we have a handle on the background of databases - and - php, this is an ideal point to mention some of the design goals behind pdo

    至此我們已經掌握了數據庫及php的背景知識，現在正好可以提及pdo背後的一些設計目標：
  2. This is because that frequency shift can also be found in the wind vortex over the arctic ocean, u - wind in beaufort sea, v - wind in east siberian sea and the pdo index

    因此，除熱力因素外，動力因素引起的海冰的平流與該變頻現象也存在一定的聯系。
  3. Pdo ( php data objects ) - a new native database abstraction layer providing performance, ease - of - use, and flexibility

    1最增的數據庫抽象層用於提供對數據庫訪問的對象，擁有良好的性能，易於使用和靈活性的特點
  4. The design philosophy for pdo is as follows

    Pdo的設計思想如下：
  5. For those of you that dislike exceptions, this is one of only two " hard - failure " points where exceptions are thrown the other is for missing transaction support when you attempt to use transactions ; for all other errors, pdo will use you choice of

    對于不喜歡異常的人來說，只有兩個「硬故障（ hard - failure ） 」點可能拋出異常，這是其中一個點（另一個地點是，當您試圖使用事務時缺乏對事務的支持） 。對于所有其他錯誤， pdo將使用您選擇的
  6. The second argument is the address of the pdo

    第二個意見是pdo的地址。
  7. N : pdo you know your height in centimeters

    你知道你身高多少厘米嗎。
  8. Now you re all set to install pdo

    現在便可以放心安裝pdo了：
  9. Oxidation than pdo ceo2 and pdo y

    氧化活性影響很大，當
  10. The pdo. so line that you added above, otherwise php won t initialize correctly

    ，否則php不能正確地初始化。
  11. To activate pdo, add the following two lines to your php. ini file

    為了激活pdo ，將下面兩行添加到php . ini文件：
  12. Follow the same steps to install and enable the pdo drivers of your choice

    使用如下相同步驟去安裝激活你選擇的pdo驅動。
  13. There are 5 key concepts that you need to be aware of, to get the most out of pdo

    為了掌握pdo ，需要了解5個關鍵概念。這5個概念是：
  14. Stacksize ( cchar ) counts the number of device objects starting from this one and descending all the way to the pdo

    堆棧大小（ cchar ）計算從這個開始的設備對象數，並且降序所有pdo方式。
  15. Each database driver that implements the pdo interface has the option of exposing additional database - specific features as regular extension functions

    實現pdo介面的每個數據庫驅動程序可以選擇公開附加的數據庫專用特性作為標準擴展功能。
  16. Pdo is modular in structure, separated into a common core that provides the api that you use in your scripts pdo itself, and one or more driver extensions that bridge pdo to the native rdbms client api libraries

    Pdo是模塊化結構，它被分成一個公共核心以及一個或多個驅動程序擴展，公共核心提供了在腳本（ pdo本身）中使用的api ，驅動程序擴展則為pdo和本地rdbms客戶機api庫架起一座橋梁。
  17. While pdo implements basic compatibility features, like ensuring autocommit is on for every database by default, or enabling bind - by - name and bind - by - position for every database driver, it will never emulate advanced database functionality like sequences or stored procedures that are not natively available for a given database

    雖然pdo實現了基本的兼容特性，比如保證每個數據庫都默認打開autocommit 、支持每個數據庫驅動程序的按名稱綁定和按位置綁定，但是如果給定的數據庫不支持序列和存儲過程這類高級數據庫功能， pdo也不可能模仿出來。
  18. In addition to setting the error code, pdo will emit a traditional e warning message

    除了設置錯誤代碼以外， pdo還將發出一條傳統的e _ warning消息。
  19. This dramatic difference is due to the light - weight forward - only cursor that is the default in pdo

    之所以有這么大的差異，是因為在pdo中默認的游標是輕量級的只能向前移動的游標。
  20. Recognizing this problem, and the opportunity represented by an object - oriented solution, the php community defined a common, object - oriented interface for data access called pdo and developed database - specific drivers that implemented the pdo interface

    認識到這個問題，再加上用面向對象解決方案來表達的想法， php定義了一種通用的面向對象的數據訪問介面稱為pdo ，並開發了實現pdo介面的數據庫專用驅動程序。
