msql_fetch_array

(PHP 3, PHP 4 , PHP 5)

msql_fetch_array -- Fetch row as array

Description

array msql_fetch_array ( resource query_identifier [, int result_type] )

Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

msql_fetch_array() is an extended version of msql_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.

The second optional argument result_type is a constant and can take the following values: MSQL_ASSOC, MSQL_NUM, and MSQL_BOTH with MSQL_BOTH being the default.

An important thing to note is that using msql_fetch_array() is NOT significantly slower than using msql_fetch_row(), while it provides a significant added value.

Avvertimento

In PHP versions prior to 4.3.11 and 5.0.4 a bug existed when retrieving data from columns containing NULL values. Such columns were not placed into the resulting array.

Esempio 1. msql_fetch_array() example

<?php
$con = msql_connect();
if (!$con) {
    die('Server connection problem: ' . msql_error());
}

if (!msql_select_db('test', $con)) {
    die('Database connection problem: ' . msql_error());
}

$result = msql_query('SELECT id, name FROM people', $con);
if (!$result) {
    die('Query execution problem: ' . msql_error());
}

while ($row = msql_fetch_array($result, MSQL_ASSOC)) {
    echo $row['id'] . ': ' . $row['name'] . "\n";
}

msql_free_result($result);
?>
