# PDOStatement::fetchAll

(no version information, might be only in CVS)

PDOStatement::fetchAll -- Returns an array containing all of the result set rows

## Description

array PDOStatement::fetchAll ( [int fetch_style])

警告
この関数は、 実験的なステータスにあります。これは、この関数の 動作、関数名、ここで書かれていること全てがPHPの将来のバージョンで予告 なく変更される可能性があることを意味します。注意を喚起するとともに自分 のリスクでこの関数を使用して下さい。

PDOStatement::fetchAll() returns an array containing all of the remaining rows in the result set. The array represents each row as either an array of column values or an object with properties corresponding to each column name. fetch_style controls the contents of the returned array as documented in PDOStatement::fetch(). fetch_style defaults to PDO_FETCH_BOTH.

Using this method to fetch large result sets will result in a heavy demand on system and possibly network resources. Rather than retrieving all of the data and manipulating it in PHP, consider using the database server to manipulate the result sets. For example, use the WHERE and SORT BY clauses in SQL to restrict results before retrieving and processing them with PHP.

例 1. Fetch all remaining rows in a result set

`<?php $sth = $dbh->prepare("SELECT name, colour FROM fruit"); $sth->execute(); /* Fetch all of the remaining rows in the result set */ print("Fetch all of the remaining rows in the result set:\n"); $result = $sth->fetchAll(); print_r($result); ?>`

上の例の出力は以下となります:

    Fetch all of the remaining rows in the result set:
    Array
    (
        [0] => Array
            (
                [NAME] => pear
                [0] => pear
                [COLOUR] => green
                [1] => green
            )

        [1] => Array
            (
                [NAME] => watermelon
                [0] => watermelon
                [COLOUR] => pink
                [1] => pink
            )

    )
