all scopes throughout a script. There is no need to do

<blockquote><p><b class="note">Note</b>:
When running on the <a href="features.commandline.php" class="link">command line
</a>, this will <em class="emphasis">not</em> include the
<a href="reserved.variables.argv.php" class="link">argv</a> and
<a href="reserved.variables.argc.php" class="link">argc</a> entries; these are

<blockquote><p><b class="note">Note</b>:
The variables in <var class="varname">$_REQUEST</var> are provided to the
script via the GET, POST, and COOKIE input mechanisms and
therefore could be modified by the remote user and cannot be
trusted. The presence and order of variables listed in this array
is defined according to the
PHP <a href="ini.core.php#ini.variables-order" class="link">variables_order</a>
configuration directive.
