    <para>
     The <function>mysqli_fetch_assoc</function> function is used to return an associative array
     representing the next row in the result set for the result represented by the
     <parameter>result</parameter> parameter, where each key in the array represents the name
     of one of the result set's columns. 
    </para>
    <para>
     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
     <function>mysqli_fetch_row</function> or add alias names.
