pg_fetch_all

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

pg_fetch_all — Fetches all rows from a result as an array

Description

pg_fetch_all(PgSql\Result $result, int $mode = PGSQL_ASSOC): array

pg_fetch_all() returns an array that contains all rows (records) in the PgSql\Result instance.

Note: This function sets NULL fields to the PHP null value.

Parameters

result

An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).

mode

An optional parameter that controls how the returned array is indexed. mode is a constant and can take the following values: PGSQL_ASSOC, PGSQL_NUM and PGSQL_BOTH. Using PGSQL_NUM, the function will return an array with numerical indices, using PGSQL_ASSOC it will return only associative indices while PGSQL_BOTH will return both numerical and associative indices.

Return Values

An array with all rows in the result. Each row is an array of field values indexed by field name.

Changelog

Version Description
8.1.0 The result parameter expects an PgSql\Result instance now; previously, a resource was expected.
8.0.0 pg_fetch_all() will now return an empty array instead of false for result sets with zero rows.
7.1.0 The mode parameter was added.

Examples

Example #1 PostgreSQL fetch all

<?php
$conn = pg_pconnect("dbname=publisher");
if (!$conn) {
echo "An error occurred.\n";
exit;
}

$result = pg_query($conn, "SELECT * FROM authors");
if (!$result) {
echo "An error occurred.\n";
exit;
}

$arr = pg_fetch_all($result);

print_r($arr);

?>

The above example will output something similar to:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => Fred
        )

    [1] => Array
        (
            [id] => 2
            [name] => Bob
        )

)
