<function>mysql_field_flags</function> returns the field flags of

the specified field. The flags are reported as a single word

per flag separated by a single space, so that you can split the

returned value using <function>explode</function>.

<para>The following flags are reported, if your version of MySQL
|

is current enough to support them: <literal>"not_null"</literal>,
