Description:
The dependency for Symfony debug recently made a change that causes problem to laravel.
str_contains function is been added in PHP v8 and Symfony added polyfill v8 dependency in recent update …but the signature is not same in laravel and if you have str_contains() with one parameter null then an error is thrown
TypeError: Argument 1 passed to str_contains() must be of the type string, null given

If you replace the dependency symfony/polyfill-php80 in your composer.json then update fails

Workaround is to forbid symfony/polyfill-php80 installation in composer.json
I perfectly works with this str_contains conflict
I just realized that there’s nothing much we can do here. Since the symfony polyfill package gets loaded first it’ll first register its
str_containsfunction. You’ll have to choose between the helpers package and the symfony one if you want to usestr_contains.The actual solution to your problem btw is to typecast to a string before attempting to use the function. The type error only happens because you’re passing in
null. Besides the fact that the newer PHP 8 function doesn’t handles multiple needles they should be complementary.I am on laravel 5.7. error still occurred. So I followed @ driesvints and @ lcharette suggestions. Updated my
str_contains()methods(only the ones which were passing needles as an array) to useStr::contains()insteadThis problem occurs too with older versions of laravel. We are working on porting over an L4 version to latest and can’t even get the vagrant dev boxes working right because of this.
As stated here, while providing the proper type is the right solution, using
Str::containsmight be helpful in the meantime.Ah, nvm you’re referring to the helpers package I see. Unfortunately these indeed collide. I’ll try to look into a solution to prevent it from being registered when you’re on PHP 8.
