PHP 7 Syntax error, question mark before specifying the parameter

Navigation
1

I developed a site at Laravel using the PHP 7.2 version, when I uploaded it to the server ( which is using version 7.0 of PHP ) I noticed that it was giving a syntax error in the following line 

public function __construct(?string $test)

This line belongs to a default framework file of Laravel

Here is the complete error:

  

mod_fcgid: stderr: PHP Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /var/www/vhosts/placarama.com.br/httpdocs/vendor/symfony/finder/Comparator/NumberComparator.php on line 42

Along with it has another error

  

mod_fcgid: stderr: PHP Fatal error: Exception thrown without a stack frame in Unknown on line 0

Does anyone have an idea what it can be?

The version does not match the new feature called Nullable types that was introduced in 7.1 version, then 7.0 does not have this feature so the errors.

Reference: Nullable types - PHP Version 7.1
