如何在MySQL/PHP中显示两位小数？

要显示两位小数，请使用 number_format()。让我们首先编写相同的 PHP 代码。我们首先声明两个变量被初始化 -

$number1=10.3423;
$number2=10;

现在，使用number_format()函数显示两个小数 −

$result1=number_format ($number1, 2);
$result2=number_format ($number2, 2);

Example

以下是示例 −

<span class="pun"><?</span><span class="pln">php</span>
<span class="pln">   $number1</span><span class="pun">=</span><span class="lit">10.3423</span><span class="pun">;</span>
<span class="pln">   $number2</span><span class="pun">=</span><span class="lit">10</span><span class="pun">;</span>
<span class="pln">   $result1</span><span class="pun">=</span><span class="pln">number_format </span><span class="pun">(</span><span class="pln">$number1</span><span class="pun">,</span><span class="pln"> </span><span class="lit">2</span><span class="pun">);</span>
<span class="pln">   $result2</span><span class="pun">=</span><span class="pln">number_format </span><span class="pun">(</span><span class="pln">$number2</span><span class="pun">,</span><span class="pln"> </span><span class="lit">2</span><span class="pun">);</span>
<span class="pln">   echo </span><span class="pun">(</span><span class="pln">$result1</span><span class="pun">);</span>
<span class="pln">   echo </span><span class="str">&#39;<br>&#39;</span><span class="pun">;</span>
<span class="pln">   echo </span><span class="pun">(</span><span class="pln">$result2</span><span class="pun">);</span>
<span class="pun">?></span>
