what does the php flag -d mean?
<p>I recently saw this page: <a href="http://stackoverflow.com/questions/4740353/php-cli-command-line-safe-mode-restriction/11134191#11134191">PHP cli command line safe_mode restriction</a></p>

<p>Where it is recommended to use the <code>-d flag</code> to override php.ini's safe mode setting like this:</p>

<pre><code>/usr/bin/php -q -d safe_mode=Off /var/www/vhosts/path-to-your-php-file.php
</code></pre>

<p>I've been searching the net for cron man, php man, php flags etc and nowhere can I find the -d flag.</p>

<p>What is it?</p>
