# sqlite_array_query

(PHP 5)

sqlite_array_query

(no version information, might be only in CVS)

SQLiteDatabase->arrayQuery -- Execute a query against a given database and returns an array

## 说明

array sqlite_array_query ( resource dbhandle, string query [, int result_type [, bool decode_binary]] )
array sqlite_array_query ( string query, resource dbhandle [, int result_type [, bool decode_binary]] )

Object oriented style (method):

class SQLiteDatabase {
array arrayQuery ( string query [, int result_type [, bool decode_binary]] )
}

sqlite_array_query() executes the given query and returns an array of the entire result set. It is similar to calling sqlite_query() and then sqlite_fetch_array() for each row in the result set. sqlite_array_query() is significantly faster than the aforementioned.

> 提示: sqlite_array_query() is best suited to queries returning 45 rows or less. If you have more data than that, it is recommended that you write your scripts to use sqlite_unbuffered_query() instead for more optimal performance.

## 参数

query

  The query to be executed.

dbhandle

  The SQLite Database resource; returned from sqlite_open () when used procedurally. This parameter is not required when using the object-oriented method.

result_type

  可选的 result_type 参数接受一个常量并决定返回的数组如何索引。用 `SQLITE_ASSOC` 只会返回关联索引（有名称字段）而 `SQLITE_NUM` 只会返回数字索引（有序字段数）。`SQLITE_BOTH` 会同时返回关联和数字索引。 `SQLITE_BOTH` 是本函数的默认值。

decode_binary

  当 decode_binary 参数设为 `TRUE`（默认值）时，PHP 将解码那些由 sqlite_escape_string() 编码的数据。通常应保留此值为其默认值，除非在操作其它支持 sqlite 程序建立的数据库时。

> 注: 为兼容其它数据库（例如 MySQL），支持另两种替代的语法。推荐用第一种，dbhandle 参数作为函数的第一个参数。

## 返回值

Returns an array of the entire result set; `FALSE` otherwise.

由 `SQLITE_ASSOC` 和 `SQLITE_BOTH` 返回的列名会根据 sqlite.assoc_case 配置选项的值来决定大小写。

## 范例

例子 1. Procedural style

`<?php $dbhandle = sqlite_open('sqlitedb'); $result = sqlite_array_query($dbhandle, 'SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC); foreach ($result as $entry) { echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email']; } ?>`

例子 2. Object-oriented style

`<?php $dbhandle = new SQLiteDatabase('sqlitedb'); $result = $dbhandle->arrayQuery('SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC); foreach ($result as $entry) { echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email']; } ?>`
