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>php</span>
   $number1</span>=</span>10.3423</span>;</span>
   $number2</span>=</span>10</span>;</span>
   $result1</span>=</span>number_format </span>(</span>$number1</span>,</span> </span>2</span>);</span>
   $result2</span>=</span>number_format </span>(</span>$number2</span>,</span> </span>2</span>);</span>
   echo </span>(</span>$result1</span>);</span>
   echo </span>\'<br>\'</span>;</span>
   echo </span>(</span>$result2</span>);</span>
?></span>
