If you're using php 5.3+, check out the <a href="http://php.net/manual/en/datetime.add.php" rel="noreferrer">DateTime::add operations</a> or <code>modify</code>, really much easier than this.

For example:

<pre><code>$startTime = new DateTime("09:00:00");
$endTime = new DateTime("19:00:00");


while($startTime &lt; $endTime) {

$startTime-&gt;modify('+30 minutes'); // can be seconds, hours.. etc

echo $startTime-&gt;format('H:i:s')."&lt;br&gt;";
break;
}
</code></pre>

blocks|key|1221548|text|使用strtotime怎么样？然后代码将是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1221549|strtotime(+'%2B30+second'+);|code-block|syntax|javascript|1221550|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

What about using strtotime? The code would then be:

<pre><code>strtotime( '+30 second' );
</code></pre>

blocks|key|1007285|text|$time+=+date("m/d/Y+h:i:s+a",+time()+%2B+30);

Would be a more explained version of all of the above.

blocks|key|1221669|text|你可以用一点不同的视角来解决这个问题。首先，可以创建一个current+datetime对象。然后，创建一个future+datetime，它比给定的日期时间晚30秒。因此，它可以归结为以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1221670|(new+Future(
++++new+Now(),
++++new+NSeconds(30)
))
++++->value();|code-block|syntax|javascript|1221671|如果您想要以您提到的特定格式输出，可以使用|1221672|(new+ISO8601Formatted(

++++'m/d/Y+h:i:s+a'

You could solve this with a bit different perspective. First, you can create a <a href="https://meringue.readthedocs.io/en/latest/faq/how_do_you_get_a_current_datetime.html" rel="nofollow noreferrer">current datetime</a> object. Then, you create a <a href="https://meringue.readthedocs.io/en/latest/faq/how_to_add_seconds_minutes_hours_days_and_all_to_php_datetime.html" rel="nofollow noreferrer">future datetime</a> which is 30 seconds later then your given datetime. So it boils down to the following:
<pre><code>(new Future(
 new Now(),
 new NSeconds(30)
))
 -&gt;value();
</code></pre>
If you want to output in a specific format you've mentioned, it can be achieved with
<pre><code>(new ISO8601Formatted(
 new Future(
 new Now(),
 new NSeconds(30)
 ),
 'm/d/Y h:i:s a'
))
 -&gt;value()
</code></pre>

How can I add 30 seconds to this time?

<pre><code>$time = date("m/d/Y h:i:s a", time());
</code></pre>

I wasn't sure how to do it because it is showing lots of different units of time, when I only want to add 30 seconds.

Add 30 seconds to the time with PHP

我怎么才能在这个时间上再加30秒呢？$time = date("m/d/Y h:i:s a", time());我不确定该怎么做，因为它显示了很多不同的时间单位，而我只想添加30秒。
