PDOStatement::fetchAll

(no version information, might be only in CVS)

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

Descrizione

array PDOStatement::fetchAll ( [int fetch_style] )

Avvertimento

Questa funzione è SPERIMENTALE. Ovvero, il comportamento di questa funzione, il nome di questa funzione, in definitiva tutto ciò che è documentato qui può cambiare nei futuri rilasci del PHP senza preavviso. Siete avvisati, l'uso di questa funzione è a vostro rischio.

Elenco dei parametri

fetch_style

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

Valori restituiti

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.

Esempi

Esempio 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
        )

)
