    <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 in the result set have the same column name, the associative array
     returned by the <function>mysqli_fetch_assoc</function> function will contain the value of
     the last column of that name. If you must work with result sets with this properity, the
     <function>mysqli_fetch_row</function> should be used which returns an numerically-indexed
     array instead.
