PDOStatement::fetchAll

(no version information, might be only in CVS)

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

Descripción

array PDOStatement::fetchAll ( [int fetch_style] )

Aviso

Esta función es EXPERIMENTAL. Esto significa que el comportamiento de esta función, el nombre de esta función y en definitiva TODO lo documentado sobre esta función, puede cambiar en una futura version de PHP SIN AVISO. La advertencia queda hecha, y utilizar esta extensión queda bajo su propia responsabilidad.

Lista de parámetros

fetch_style

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

Valores retornados

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.

Ejemplos

Ejemplo 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);
?>

El resultado del ejemplo seria:

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
        )

)
