Returns an associative array with directive name as the array key.

<para>
When <parameter>details</parameter> is &true; (default) the array will
contain <literal>global_value</literal> (set in

<function>ini_set</function> or &htaccess;), and
<literal>access</literal> (the access level).

<para>
When <parameter>details</parameter> is &false; the value will be the
current value of the option.

<para>
See the <link linkend="configuration.changes.modes">manual section</link>
for information on what access levels mean.
</para>
<note>
<para>
It's possible for a directive to have multiple access levels, which is
why <literal>access</literal> shows the appropriate bitmask values.
