奇怪~！原来好用的程序怎么不好用了？错在那里？请指教~~!

Question

没有问题呀
$pageParams['totaloper'] = 1.00 // out 1
$pageParams['totaloper'] = 1.01 // out 1.01

Answer 1

怎么搞得？我这里确实是显示的不正常。我把整个的代码贴出来，请大家帮我看看。var_dump($pageParams['operationinfo'][$count]['totaloper']);
if (ceil($pageParams['operationinfo'][$count]['totaloper']) == $pageParams['operationinfo'][$count]['totaloper']) 
{
   $pageParams['operationinfo'][$count]['totaloper']=$pageParams['operationinfo'][$count]['totaloper'];
}else 
{
   $pageParams['operationinfo'][$count]['totaloper']=number_format($pageParams['operationinfo'][$count]['totaloper'], 2, ".", "");
 }
var_dump($pageParams['operationinfo'][$count]['totaloper']);
exit;
我是把这段代码做在了一个循环当中。在处理之前我输出了这个值，是整数；可是在处理之后又输出了这个值却变成了string型的，.00的样子了。输出结果如下：float(100)    string(6) "100.00" 为什么是这样的呢？

这是我的测试，的确没有你说的情况。
不过如果$pageParams['operationinfo'][$count]['totaloper'] 的值是计算得来的，是有可能的，你可以先用round($pageParams['operationinfo'][$count]['totaloper'],2)先处理一下
<?php
$count = 1;
$pageParams['operationinfo'][$count]['totaloper'] = 1.00;
var_dump($pageParams['operationinfo'][$count]['totaloper']);
if (ceil($pageParams['operationinfo'][$count]['totaloper']) == $pageParams['operationinfo'][$count]['totaloper']) 
{
   $pageParams['operationinfo'][$count]['totaloper']=$pageParams['operationinfo'][$count]['totaloper'];
}else 
{
   $pageParams['operationinfo'][$count]['totaloper']=number_format($pageParams['operationinfo'][$count]['totaloper'], 2, ".", "");
 }
var_dump($pageParams['operationinfo'][$count]['totaloper']);
exit;?>
