The is an important difference from the traditional php database extensions 這與傳統的php數據庫擴展有很大的不同。
Pfl ( persistent functional language ) is a simple functional language with database extensions Pfl是一種簡單函數語言,它帶有數據庫擴展。
It is important to note that you may not mix this method of fetching with the bulk fetching methods like mdb : : fetchall ( ) as this will cause problems in most php database extensions 注意你不要把這個獲取函數和bulk獲取函數像mdb : : fetchall ( )搞混了,因為這將在大部分php數據庫擴展中導致問題。
To establish a cached connection or pconnect if you re more familiar with the traditional database extensions , you pass in an attribute when you instantiate your database connection 要建立一個緩存的連接(如果您更熟悉傳統的數據庫擴展的話,也可以說是* pconnect ( ) ) ,需要在實例化數據庫連接時傳遞一個屬性:
Each extension claims a different functional namespace - for example , the mysql connect and ibase connect return database connections for mysql and firebird interbase , respectively - and each extension implements its own api with sometimes minor but confusing variations from other database extensions 每個擴展都聲明了不同的功能性名稱空間,比如mysql _ connect ( )和ibase _ connect ( )分別返回mysql和firebird / interbase的數據庫連接;每個擴展都實現了自己的api ,與其他數據庫擴展之間有一些微小卻容易混淆的差別。
However , not all database client apis are the same , and not all databases offer the same features ; despite the mimicry , the various php database extensions have their own quirks and differences that make migration from one database to another into something of a difficult prospect 然而,并不是所有的數據庫客戶機api都是一樣的,也不是所有的數據庫都提供相同的特性。雖然存在模仿,但不同的php數據庫擴展都有它們各自的怪僻和不同之處,所以從一種數據庫遷移到另一種數據庫時會有一些困難。
