PHP microtime - microseconds format <p>If PHP's <code>microtime()</code> function were to be executed at a point in time where the resulting microseconds are <strong>zero</strong>, what format does it result in?</p> <p><strong>Would it look like this?</strong></p> <p><code>0.00 1467926279?</code></p> <p><strong>Or this?</strong></p> <p><code>0 1467926279</code></p> <p><a href="http://php.net/manual/en/function.microtime.php" rel="nofollow">The manual</a> doesn't provide a numerical format, just it's format in English: </p> <blockquote> <p>By default, microtime() returns a string in the form "msec sec"</p> </blockquote>
