pg_fetch_result

pg_fetch_result

(PHP 4 >= 4.2.0, PHP 5)

pg_fetch_result从结果资源中返回值

说明

mixed pg_fetch_result ( resource $result , int $row , mixed $field )

pg_fetch_result() 根据由 pg_query() 返回的 result 资源返回相应的值。row 为整型数。field 为字段名(字符串)或字段索引(整数)。rowfield 指明了查询结果中的哪个单元被返回。行编号从 0 开始。除了用字段名之外,还可以用不带引号的数字作为字段索引。字段索引从 0 开始。

PostgreSQL 有很多内置的类型,这里只直接支持基本类型。所有形式的 integerboolean 和 void 类型都被返回为 integer 值。所有形式的 float 和 real 类型都被返回为 float 值。Boolean 类型被返回为 "t" 或者 "f"。所有其它类型包括数组都被返回为字符串,该字符串的格式和默认的 PostgreSQL 风格一样,可以在 psql 程序中看到。
