在哪里添加int $decimals = 0？

Question

我需要打印一个有两个小数点的数字，我相信我使用了这段代码int $decimals = 0，但我不知道我需要把它加到哪里。

下面是我的代码：

<?php 
  $tempPrice = str_replace(',',"", $price); //gets rid of "," 
  $tempPrice = substr($tempPrice,2); //removes currency from the front
  $tempPrice = floatval($tempPrice); //converts to double from string

  if($tempPrice > 1000) 
  {
    echo '£' . round(($tempPrice*0.038), 2) . ' per month';
  }
  else 
  {
    echo 'Lease to buy price not available on this product';
  }
 ?>

谢谢

您可以使用money_format() php函数。http://php.net/money_format

例如在您的情况下

<?php 
  $tempPrice = str_replace(',',"", $price); //gets rid of "," 
  $tempPrice = substr($tempPrice,2); //removes currency from the front
  $tempPrice = floatval($tempPrice); //converts to double from string
  // set international format for the en_GB locale
  setlocale(LC_MONETARY, 'en_GB');    
  if($tempPrice > 1000) 
  {
  echo money_format('%i', $tempPrice ) . " per month";// output->"GBP 1,234.56 per month"
  }
  else 
  {
    echo 'Lease to buy price not available on this product';
  }
 ?>

此外，您还可以在$tempPrice上使用php number_format() http://php.net/number_format

echo "£ ". number_format($tempPrice ) . " per month";

默认情况下，使用number_format()英语表示法。您可以设置自己的小数点数、小数点设置符和千位分隔符

echo "£ ". number_format($tempPrice, 2, ".", "," ) . " per month"; // for $tempPrice=1203.52 output will be "£ 1,203.56 per month"
