Solve issue of upgrading to php 7.2 in laravel 5.4 application
提问by atieh mokhtary
I have Upgraded my laravelapplication php version to php 7.2this week and from then I am facing big problems in my laravelapplication. before upgrading php to 7.2every thing worked pefectly.
本周我已将我的Laravel应用程序 php 版本升级到php 7.2，从那时起我在我的Laravel应用程序中遇到了大问题。在将php升级到 7.2之前，一切正常。
the main issue is about count()and array_merge()functions which is throwing this error:
主要问题是关于引发此错误的count()和array_merge()函数：
for array_merge()function the code is as below:
为array_merge()函数的代码是如下：
$array = array_merge(
$model->toSearchableArray(), $model->scoutMetadata()
);
if (empty($array)) {
return;
}
ErrorException · array_merge(): Argument #1 is not an array.
ErrorException · array_merge()：参数 #1 不是数组。
and I am facing count()error for example at this code when the model returns no records and returns null:
count()例如，当模型不返回记录并返回空值时，我在此代码中遇到错误：
count(TutorialReview::where('TutorialID', 5)->where('UserID', 6)->get())
count(): Parameter must be an array or an object that implements Countable.
count(): 参数必须是一个数组或一个实现 Countable 的对象。
my laravel version is 5.4
我的 Laravel 版本是5.4
now my question is how can I solve the issues, and does upgrading to laravel 5.5solve any of the issues?
现在我的问题是如何解决这些问题，升级到Laravel 5.5 是否可以解决任何问题？

In PHP 7.2changed count()behavior in the following RFC: https://wiki.php.net/rfc/counting_non_countables
在PHP 7.2 中更改count()了以下 RFC 的行为：https: //wiki.php.net/rfc/counting_non_countables
But you can get count using ->count()in laravel, here is an example of it:
但是你可以->count()在laravel 中使用计数，这是一个例子：
$count = TutorialReview::where('TutorialID', 5)->where('UserID', 6)->get()->count();
This way you can get total records count.
这样您就可以获得总记录数。

Just add @before count. I.E.
@之前添加count。IE
@count(object or array);

To solve array_merge() issue, try those steps:
要解决 array_merge() 问题，请尝试以下步骤：
sluggable.php config file at app/config with data
return ['source' => null, 'maxLength' => null, 'method' => null, 'separator' => '-', 'unique' => true, 'uniqueSuffix' => null, 'includeTrashed' => false, 'reserved' => null, 'onUpdate' => false, ];Execute the command,
php artisan config:cache
带有数据的 app/config 中的 sluggable.php 配置文件
return ['source' => null, 'maxLength' => null, 'method' => null, 'separator' => '-', 'unique' => true, 'uniqueSuffix' => null, 'includeTrashed' => false, 'reserved' => null, 'onUpdate' => false, ];执行命令，
php artisan config:cache
To solve count() issue: Try This
解决 count() 问题：试试这个
count(): Parameter must be an array or an object that implements Countable.
Actually its not a error , its an expected behavior . Laravel 5.4 or 5.5 is not fully compatible with Php 7.2 . Count() behaviour just change at PHP 7.2 Look at this
实际上它不是错误，而是预期的行为。Laravel 5.4 或 5.5 与 PHP 7.2 不完全兼容。Count() 行为只是在 PHP 7.2 中改变 看看这个
Another way just use PHP 7.1 or below until compatibility issue fixed.
另一种方法是使用 PHP 7.1 或更低版本，直到兼容性问题得到解决。

try this:
尝试这个：
$array = array_merge(
collect($model->toSearchableArray())->toArray(), $model->scoutMetadata()
);
also when counting model instance do this by ->count()instead of count()
也在计算模型实例时这样做->count()而不是count()

just add below code in web.php
只需在 web.php 中添加以下代码
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
}

in PHP 7.2 Count Method i not available due to security reason you need to install extension for that look at that documentation
在 PHP 7.2 Count Method 中，由于安全原因，您需要安装扩展以查看该文档
