Cannot redeclare Safe\array_combine()

[j3j5]

Hi there, congrats on the project, I just discovered it and I think is great.

Now, I've tried to add it to one of my libraries and now when I run phpstan (with our without the rule) I get the following error:

PHP Fatal error:  Cannot redeclare Safe\array_combine() (previously declared in /home/user/project/vendor/thecodingmachine/safe/generated/array.php:20) in /home/user/project/vendor/thecodingmachine/safe/generated/array.php on line 20

Fatal error: Cannot redeclare Safe\array_combine() (previously declared in /home/user/project/vendor/thecodingmachine/safe/generated/array.php:20) in /home/user/project/vendor/thecodingmachine/safe/generated/array.php on line 20

In array.php line 20:
                                                                                                                                                              
  Cannot redeclare Safe\array_combine() (previously declared in /home/user/project/vendor/thecodingmachine/safe/generated/array.php:20)  
                                                                                                                                                              

The file obviously don't have the function declared twice and I'm completely lost as for where it could be coming from. Any ideas? I'm on 1.3.3.

Thanks!

I don't know sorry. Do you still have the issue if you remove the library and re install it with composer?

[j3j5]

Steps to reproduce:

• Clone this repo
• Run composer install
• Run ./vendor/bin/phpstan analyse

It should be reproducible on your machine, I'm using PHP 7.4.11 just in case it has anything to do.

I've been digging a bit further, the issue is only with the array_ functions but I can't find why phpstan thinks they've been previously declared. If I remove the line from composer.json that includes the array.php file and dump the autoloader classes again, phpstan runs just fine.

It is a very strange issue.

FWIW, installing the library on another project and using it doesn't seem to throw the error, so everything points to an error on phpstan and how it loads the autoloader, but I have no idea where else to look.

Do you have any updates on this?

This is still an issue. Just ran into it myself.

Edit after annoyed post:
I've pinned it down to the usage of Safe\dns_get_record();

When I omit this from my codebase it works fine.
thecodingmachine/safe: v1.3.3
nunomaduro/larastan: v0.6.13

It seems like the function_exists call is dropped, and the issue is a thing again.

It's happening on 2.1.2 for me too.

In combination with phpstan or rector, the error still occurs (v2.1.2).

As pointed out in #253 (comment), this issue is exclusive to the phpstan extension. As far as I can tell, we only declare Safe\array_combine once (see: https://github.com/thecodingmachine/safe/search?q=array_combine%28).

There is a bug report in the phpstan safe extension for this: thecodingmachine/phpstan-safe-rule#29, let's continue discussion there.

That said, I have no idea what causes this atm. If anyone is willing to look into it, go ahead!

I've re-opened this issue per thecodingmachine/phpstan-safe-rule#29 (comment)

I have same problem. But function is array_flip.

PHP Fatal error: Cannot redeclare Safe\array_flip(),

thecodingmachine/safe: v2.1.2
nunomaduro/larastan: 1.0.3
