mysql_fetch_assoc

Description

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

mysql_fetch_assoc() is equivalent to calling mysql_fetch_array() with MYSQL_ASSOC for the optional second parameter. It only returns an associative array. This is the way mysql_fetch_array() originally worked. If you need the numeric indices as well as the associative, use mysql_fetch_array().

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 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.

<?php
    mysql_connect("localhost", "mysql_user", "mysql_password");
    mysql_select_db("mydb");
    $query = "select * from table";
    $result = mysql_query($query);
    while ($row = mysql_fetch_assoc($result)) {
        echo $row["user_id"];
        echo $row["fullname"];
    }
    mysql_free_result($result);
?>
