title: Laravel 5.7 on apache error Call to undefined function Illuminate\Encryption\openssl_cipher_iv_length()
body: <p>I'm setting Laravel 5.7 on Apache 2.4 using PHP 7.1.26.
  I configured everything like documentations.
  But I'm getting the error below:</p>
  
  <blockquote>
    <p>Call to undefined function Illuminate\Encryption\openssl_cipher_iv_length()</p>
  </blockquote>
  
  <p>I've already change PHP version to 7.2 and nothing.
  I've already copied the file libeay32.dll to Apache and nothing</p>
  
  <p>These are my modules in PHP</p>
