<code>$num + 0</code> does the trick.

<pre><code>echo 125.00 + 0; // 125
echo '125.00' + 0; // 125

Internally, this is equivalent to casting to float with <code>(float)$num</code> or <code>floatval($num)</code> but I find it simpler.

N.B. This assumes <code>.</code> is the decimal separator. It has the advantage that it will work on arbitrarily large (or small) numbers since there is no float cast. It also won't turn numbers into scientific notation (e.g. 1.0E-17).

Due to this question is old. First, I'm sorry about this.

The question is about number xxx.xx but in case that it is x,xxx.xxxxx or difference decimal separator such as xxxx,xxxx this can be harder to find and remove zero digits from decimal value.

 * @param string The decimal separator. You have to set this parameter to exactly what it is. For example: in Europe it is mostly use "," instead of ".".
 * @return string Return removed zero digits from decimal value.

 $this-&gt;tsepparator = $langDatas[$usersLang]['tsepparator'];

blocks|key|391319|text|终极解决方案:唯一安全的方法是使用正则表达式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391320|echo+preg_replace("/\.?0%2B$/",+"",+3.0);+//+3
echo+preg_replace("/\d%2B\.?\d*(\.?0%2B)/",+"",+3.0);+//+3|code-block|syntax|javascript|391321|它适用于任何情况|391322|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Ultimate Solution: The only safe way is to use regex:

<pre><code>echo preg_replace("/\.?0+$/", "", 3.0); // 3
echo preg_replace("/\d+\.?\d*(\.?0+)/", "", 3.0); // 3
</code></pre>

it will work for any case

blocks|key|391326|text|下面的代码要简单得多|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391327|if(floor($num)+==+$num)+{
++++echo+number_format($num);
}+else+{
++++echo+$num;
}|code-block|syntax|javascript|391328|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|$]]

The following is much simpler

<pre class="lang-php prettyprint-override"><code>if(floor($num) == $num) {
 echo number_format($num);
} else {
 echo $num;
}
</code></pre>

blocks|key|391345|text|您可以尝试以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391346|rtrim(number_format($coin->current_price,6),'0.')|code-block|syntax|javascript|391347|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|$]]

You can try the following:
<pre class="lang-php prettyprint-override"><code>rtrim(number_format($coin-&gt;current_price,6),'0.')
</code></pre>

I'm trying to find a fast way to remove <code>zero decimals</code> from number values like this:

<pre><code>echo cleanNumber('125.00');
// 125

echo cleanNumber('966.70');
// 966.7

echo cleanNumber(844.011);
// 844.011
</code></pre>

Does exists some optimized way to do that?

Remove useless zero digits from decimals in PHP

我正在尝试找到一种从数值中删除zero decimals的快速方法，如下所示：echo cleanNumber('125.00');// 125echo cleanNumber('966.70');// 966.7echo cleanNumber(844.011);// 844.011有没有一些优化的方法可以做到这一点？
