PHP 7.2 count() function is not working
提问by Nilay Singh
I have a working php application and it is running fine on php 7.0 version. But when I upgrade a php version to 7.2. I am getting this error:
我有一个可用的 php 应用程序，它在 php 7.0 版本上运行良好。但是当我将 php 版本升级到 7.2 时。我收到此错误：
count(): Parameter must be an array or an object that implements Countable
I am getting errors on code where I am comparing my data with count function. For example this is my code:
我在将数据与计数函数进行比较的代码中遇到错误。例如这是我的代码：
$keytest = KeyUser::where('key', '=', $key)->first();
if (count($keytest) == 1) {
//logic ...
}
I am using laravel where I am running a query and counting it if it is equal to 1 then logic should work.
我正在使用 laravel 运行查询并计算它，如果它等于 1，那么逻辑应该可以工作。
So my problem is I have written this kind of logic on many controllers and if I have to change everything one by one it could become nightmare. So is there any way where I can write a global function to make count work as it was working in php older version. What can be the easiest fix.
所以我的问题是我已经在许多控制器上编写了这种逻辑，如果我必须一个一个地更改所有内容，它可能会成为噩梦。那么有什么方法可以编写一个全局函数来使计数在 php 旧版本中工作。什么是最简单的修复。

This problem can be handle using disable error handling. Please refer this link for solution: Laravel not compatiable with php 7.2
可以使用禁用错误处理来处理此问题。请参阅此链接以获取解决方案：Laravel not compatiable with php 7.2
Here I found a solution to your problem simply write this code inside your controller or if you want to make it work for whole application write this code in route.php:
在这里，我找到了解决您的问题的方法，只需在您的控制器中编写此代码，或者如果您想让它适用于整个应用程序，请在 route.php 中编写此代码：
//app/Http/routes.php
if (version_compare(PHP_VERSION, '7.2.0', '>=')) {
// Ignores notices and reports all other kinds... and warnings
error_reporting(E_ALL ^ E_NOTICE ^ E_WARNING);
// error_reporting(E_ALL ^ E_WARNING); // Maybe this is enough
}
I know this is not the best solution but it can be a good hack.
我知道这不是最好的解决方案，但它可以是一个很好的黑客。

It's solved when you change your code:
当您更改代码时，它已解决：
$keytest = KeyUser::where('key', '=', $key)->first();
if ($keytest) {
//logic ...
}
