sqlite_column -- SQLiteResult::column -- SQLiteUnbuffered::column — Fetches a column from the current row of a result set

说明

sqlite_column ( resource $result , mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed
SQLiteResult::column ( mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed
SQLiteUnbuffered::column ( mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed

Fetches the value of a column named index_or_name (if it is a string), or of the ordinal column numbered index_or_name (if it is an integer) from the current row of the query result handle result.

参数

result

The SQLite result resource. This parameter is not required when using the object-oriented method.

index_or_name

The column index or name to fetch.

decode_binary

当 decode_binary 参数设置为 TRUE（默认值）时，PHP 会解码那些由 sqlite_escape_string() 编码后的二进制数据。通常应保留此值为其默认值，除非要与其他使用 SQLlite 的应用程序建立的数据交互。

返回值

Returns the column value.

注释

Note:

Use this function when you are iterating a large result set with many columns, or with columns that contain large amounts of data.
