# 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
這個函數是實驗性質的。這個函數的行為、名稱、和關於此函數的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此延伸需自行承擔風險。

## Parameters

fetch_style

  Controls the contents of the returned array as documented in PDOStatement::fetch(). Defaults to PDO_FETCH_BOTH.

## Return Values

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.

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.

## 範例

範例 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); ?>`
The above example will output:
    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
            )

    )
