| 1. | The is an important difference from the traditional php database extensions
这与传统的php数据库扩展有很大的不同。 |
| 2. | Pfl ( persistent functional language ) is a simple functional language with database extensions
Pfl是一种简单函数语言，它带有数据库扩展。 |
| 3. | 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
注意你不要把这个获取函数和bulk获取函数像mdb : : fetchall ( )搞混了，因为这将在大部分php数据库扩展中导致问题。 |
| 4. | 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
要建立一个缓存的连接（如果您更熟悉传统的数据库扩展的话，也可以说是* pconnect ( ) ） ，需要在实例化数据库连接时传递一个属性： |
| 5. | 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
每个扩展都声明了不同的功能性名称空间，比如mysql _ connect ( )和ibase _ connect ( )分别返回mysql和firebird / interbase的数据库连接；每个扩展都实现了自己的api ，与其他数据库扩展之间有一些微小却容易混淆的差别。 |
| 6. | 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，并不是所有的数据库客户机api都是一样的，也不是所有的数据库都提供相同的特性。虽然存在模仿，但不同的php数据库扩展都有它们各自的怪僻和不同之处，所以从一种数据库迁移到另一种数据库时会有一些困难。 |
