Uncaught TypeError: must be an instance of mixed or null, string given
farhadsakhaei opened this issue · comments
Hi,
Bug Description
I set the php version to 7.0
I have a code that used mixed in function parameter argument
But seems that PHP 7.0 doesn't support this
But I didn't get any error for such things
PHP Error LOG:
E_ERROR class-file.php : Uncaught TypeError: Argument 1 passed to __construct() must be an instance of mixed or null, string given
Given the following reproduction Scenario
public static function get_instance( mixed $param = null ) {
and return type:
public static function get_instance( mixed $param = null ) :mixed{
... with this custom ruleset:
<?xml version="1.0"?>
<config name="testVersion" value="7.0-"/>
@farhadsakhaei Please use the bug template as there is now too little information for us to help you.
PHPCompatibility reports on the mixed type without issue.

Hi, Thank you for your reply,
mixed type is not compatible with PHP 7.0
And PHPCS doesn't warn for that
@farhadsakhaei Correct, it does not warn, it throws an error.
@jrfnl
It doesn't throw error:
phpcs -p . --standard=PHPCompatibility --runtime-set testVersion 7.0-
..................... 21 / 21 (100%)
Time: 384ms; Memory: 10MB
My code cotains:
function blabla(mixed $param1) {
or
function blabla(): mixed {
And I use PHP 8.3.2, is it matter?
I just need to make my code compatible with PHP 7.0 too
@farhadsakhaei That might depend on the version of PHPCompatibility you are using. Again: use the bug template to provide us with the necessary information.

I was using PHPCompatibility 9.3.5,
I just installed it using composer.
"phpcompatibility/php-compatibility": "*",
is there any another repo to install using composer?
I just uploaded the current github repo and it fixed the problem,
How can I install latest versions using composer?
Thank you
@jrfnl
Thank you for your help
I hope you release version 10 soon
