sqlite_fetch_all Fetches all rows from a result set as an array of arrays


sqlite_fetch_all

SQLiteResult->fetchAll

SQLiteUnbuffered->fetchAll

(PHP 5, PECL sqlite >= 1.0.0)

sqlite_fetch_all -- SQLiteResult->fetchAll -- SQLiteUnbuffered->fetchAllFetches all rows from a result set as an array of arrays

说明

array sqlite_fetch_all ( resource $result [, int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] )

Object oriented style (method):

array SQLiteResult::fetchAll ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] ) array SQLiteUnbuffered::fetchAll ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] )

sqlite_fetch_all() returns an array of the entire result set from the result resource. It is similar to calling sqlite_query() (or sqlite_unbuffered_query()) and then sqlite_fetch_array() for each row in the result set.

参数

result

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

result_type

可选的 result_type 参数接受常量,且决定返回的数组如何被索引。使用 SQLITE_ASSOC 会仅返回关联索引(已命名字段),而 SQLITE_NUM 会仅返回数值索引。SQLITE_BOTH 会同时返回关联和数值索引。SQLITE_BOTH 是此函数的默认值。

decode_binary

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 an array of the remaining rows in a result set. If called right after sqlite_query(), it returns all rows. If called after sqlite_fetch_array(), it returns the rest. If there are no rows in a result set, it returns an empty array.

SQLITE_ASSOCSQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。

范例

Example #1 Procedural example

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

Example #2 Object-oriented example

<?php
$dbhandle 
= new SQLiteDatabase('sqlitedb');

$query $dbhandle->query('SELECT name, email FROM users LIMIT 25'); // buffered result set
$query $dbhandle->unbufferedQuery('SELECT name, email FROM users LIMIT 25'); // unbuffered result set

$result $query->fetchAll(SQLITE_ASSOC);
foreach (
$result as $entry) {
    echo 
'Name: ' $entry['name'] . '  E-mail: ' $entry['email'];
}
?>
