# PDOStatement::fetchAll

(no version information, might be only in CVS)

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

## Beskrivelse

array PDOStatement::fetchAll ( [int fetch_style] )

Advarsel
Denne funktion er EKSPERIMENTABEL. Virkemåden af denne funktion, navnet på funktionen, og andet ellers dokumenteret om denne funktion, ændres muligvis uden advarsel i en fremtidig version af PHP. Brug af denne funktion er på ejet ansvar.

## Parameterliste

fetch_style

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

## Returneringsværdier

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.

## Eksempler

Eksempel 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); ?>`

Ovenstående eksempel vil udskrive:

    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
            )

    )
