mysqli_fetch_array

(PHP 5 CVS only)

mysqli_fetch_array -- Fetch a result row as an associative, a numeric array, or both.

Description

array mysqli_fetch_array ( resource result [, int resulttype])

Returns an array that corresponds to the fetched row or FALSE if there are no more rows for the database connection represented by the link parameter.

mysqli_fetch_array() is an extended version of the mysqli_fetch_row() function. In addition to storing the data in the numeric indices of the result array, the mysqli_fetch_array() function can also store the data in associative indices, using the field names of the result set as keys.

Note: Field names returned by this function are case-sensitive.

If two or more columns of the result have the same field names, the last column will take precedence and overwrite the earlier data. In order to access multiple columns with the same name, the numerically indexed version of the row must be used.

The optional second argument result_type is a constant indicating what type of array should be produced from the current row data. The possible values for this parameter are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH. By default the mysqli_fetch_array() function will assume MYSQLI_BOTH for this parameter.

By using the MYSQLI_ASSOC constant this function will behave identically to the mysqli_fetch_assoc(), while MYSQLI_NUM will behave identically to the mysqli_fetch_row() function. The final option MYSQLI_BOTH will create a single array with the attributes of both.

Example 1. mysqli_fetch_array with MYSQLI_NUM

<?php
    mysqli_connect("localhost", "mysql_user", "mysql_password") or
        die("Could not connect: " . mysqli_error());
    mysqli_select_db("mydb");

    $result = mysqli_query("SELECT id, name FROM mytable");

    while ($row = mysqli_fetch_array($result, MYSQLI_NUM)) {
        printf ("ID: %s  Name: %s", $row[0], $row[1]);  
    }

    mysqli_free_result($result);
 ?>

Example 2. mysqli_fetch_array with MYSQLI_ASSOC

<?php
    mysqli_connect("localhost", "mysql_user", "mysql_password") or
        die("Could not connect: " . mysqli_error());
    mysqli_select_db("mydb");

    $result = mysqli_query("SELECT id, name FROM mytable");

    while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
        printf ("ID: %s  Name: %s", $row["id"], $row["name"]);
    }

    mysqli_free_result($result);
 ?>

Example 3. mysqli_fetch_array with MYSQLI_BOTH

<?php
    mysqli_connect("localhost", "mysql_user", "mysql_password") or
        die("Could not connect: " . mysqli_error());
    mysqli_select_db("mydb");

    $result = mysqli_query("SELECT id, name FROM mytable");

    while ($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {
        printf ("ID: %s  Name: %s", $row[0], $row["name"]);
    }

    mysqli_free_result($result);
 ?>
