我正在处理的一个项目中有一些PHP代码,这些代码使用PHP的round函数。在我的本地主机上,我没有在我的模式参数前后加上任何引号,只是将其声明为PHP_ROUND_HALF_DOWN。然而,当推送到我的服务器时,我得到了错误消息:
Use of undefined constant PHP_ROUND_HALF_DOWN - assumed 'PHP_ROUND_HALF_DOWN'
Warning (2): Wrong parameter count for round() [APP/views/helpers/time_left.php, line 14]
现在,当我将单
当使用ms excel文件导入excel时,无法工作,请获取此错误

我一直在处理一个PHP表单,它可以更改服务器上文件中的值。表单正确地更改了值,但我需要表单的<option value="round" <?php if($shape == 'round'){?>selected="selected"<?php }?>>Round</option>部分始终显示在文件中设置的当前值,目前它不是。
#file contents (the lines the values are on changed on a regular basis)

我需要一个函数可以从定义的自定义范围.
例如:
0.01 - 0.39 = round to 0
0.40 - 0.74 = round to 0.5
0.75 - 0.99 = round to 1
if number is 2.33 it should show as 2.0
if number is 2.67 it should show as 2.5
if number is 2.89 it should show as 3.0
我试过一些东西,但一点也不管用.
代码:
$range1 = range(0.01, 0.39, 0.01);
$range2 = range(0.40,
我已经试了好几个小时了,但我看不出有什么错误。我有一个模型‘用户’和一个模型‘圆’。我想定义一个n:m-关系与一个模型‘飞行’作为枢轴模型。
User.php

其实没什么好解释的,我只是想不出在include URL中使用变量的正确语法
以下是我认为的结果:
$round_num=1;
include '../../fixtures/round{$round_num}fix.php';
它返回通常的:
Warning: include(../../fixtures/round{$round_num}fix.php) [function.include]: failed to open stream: No such file or directory
这对在座的各位来说一定很简单,但是我就是找不到我的答案!
我的网站在我的本地主机上运行得很好。但是,当我将最新的东西上传到服务器时,我得到了以下错误:

Student.php
它有很多费用
class student extends Model{
public function fees($round){
return $this->hasMany(fee::class)->where('payment_round','=',$round);
}
}
Fee.blade.php
@foreach($student->fees("parameter") as $fee)
{{$fee->myproperty}}
@endforeach
