title: Lumen/Laravel 6: Call to undefined function array_except()
body: <p>So my Mailable view is throwing this error - and this is all I have on my hands. It was working fine while I was on Lumen 5.8, so my guess is that it happened after upgrading to Laravel 6.</p>
  
  <blockquote>
    <p>Call to undefined function array_except() (View:
    /kunden/182801_60322/tu/uat/api/resources/views/mail/invite-employee.blade.php)</p>
  </blockquote>
  
  <p>My blade file looks like this:</p>
  
  <pre><code>@extends('mail.master')
  
  @section('content')
  &lt;tr&gt;
      &lt;td align="left" style="border: 1px solid #dddee5; border-bottom: 2px solid #cecfd9; padding; 20px;"&gt;
          &lt;div class="padded"&gt;
              &lt;p&gt;
              {!! nl2br(e($data-&gt;message)) !!}
              &lt;/p&gt;
          &lt;/div&gt;
      &lt;/td&gt;
  &lt;tr&gt;
  &lt;tr&gt;
      &lt;td align="left" bgcolor="#eaeaf2" class="padded"&gt;
          &lt;p style="margin-bottom: 5px;" class="cta-label"&gt;{{ $data-&gt;copy-&gt;click }}&lt;/p&gt;
          &lt;div class="cta-link"&gt;
              &lt;a style="color: #337BE9;" class="cta-link--a" href="{{ $data-&gt;appUrl }}/{{ $data-&gt;route }}/{{ $data-&gt;verificationCode }}"&gt;{{ $data-&gt;appUrl }}/{{ $data-&gt;route }}/{{ $data-&gt;verificationCode }}&lt;/a&gt;
          &lt;/div&gt;
          &lt;p style="font-size: 12px; margin-top: 10px;"&gt;{{ $data-&gt;copy-&gt;mistake }}&lt;/p&gt;
      &lt;/td&gt;
  &lt;/tr&gt;

  <p>where obviously no part of the code is trying to call that function.</p>

  <p>where the <code>laravel/helpers</code> are also included now, separately. Nothing has helped so far. Any ideas what is causing this error?</p>
