mysql_fetch_assoc

Fetch a result row as an associative array

&mysql.alternative.note;

- `mysqli_fetch_assoc`
- `PDOStatement::fetch` with `mode` as `PDO::FETCH_ASSOC`

&reftitle.description; `array` `mysql_fetch_assoc` `resource` `result`

Returns an associative array that corresponds to the fetched row and moves the internal data pointer ahead. `mysql_fetch_assoc` is equivalent to calling `mysql_fetch_array` with MYSQL_ASSOC for the optional second parameter. It only returns an associative array.

&reftitle.parameters;

&mysql.result.description;
&reftitle.returnvalues;

Returns an associative array of strings that corresponds to the fetched row, or &false; if there are no more rows.

If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you either need to access the result with numeric indices by using `mysql_fetch_row` or add alias names. See the example at the `mysql_fetch_array` description about aliases.

### An expanded `mysql_fetch_assoc` example

    <?php

    $conn = mysql_connect("localhost", "mysql_user", "mysql_password");

    if (!$conn) {
        echo "Unable to connect to DB: " . mysql_error();
        exit;
    }

    if (!mysql_select_db("mydbname")) {
        echo "Unable to select mydbname: " . mysql_error();
        exit;
    }

    $sql = "SELECT id as userid, fullname, userstatus
            FROM   sometable
            WHERE  userstatus = 1";

    $result = mysql_query($sql);

    if (!$result) {
        echo "Could not successfully run query ($sql) from DB: " . mysql_error();
        exit;
    }

    if (mysql_num_rows($result) == 0) {
        echo "No rows found, nothing to print so am exiting";
        exit;
    }

    // While a row of data exists, put that row in $row as an associative array
    // Note: If you're expecting just one row, no need to use a loop
    // Note: If you put extract($row); inside the following loop, you'll
    //       then create $userid, $fullname, and $userstatus
    while ($row = mysql_fetch_assoc($result)) {
        echo $row["userid"];
        echo $row["fullname"];
        echo $row["userstatus"];
    }

    mysql_free_result($result);

    ?>

### Performance

An important thing to note is that using `mysql_fetch_assoc` is not significantly slower than using `mysql_fetch_row`, while it provides a significant added value.
