and let?s assume the following content of Bar.php:
// Bar.phpnamespaceOtherDir;useSomeDir\Foo;// This now conflicts the class OtherDir\Foo
If both files OtherDir/Foo.php and SomeDir/Foo.php are loaded in the
same runtime, you will see a PHP error such as the following:
PHP Fatal error: Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php
However, as OtherDir/Foo.php does not necessarily have to be loaded and the
error is only triggered if it is loaded before OtherDir/Bar.php, this problem
might go unnoticed for a while. In order to prevent this error from surfacing,
you must import the namespace with a different alias:
// Bar.phpnamespaceOtherDir;useSomeDir\FooasSomeDirFoo;// There is no conflict anymore.

It seems like get_post_meta($post_id, ...ic_gateway_mode', true) can also be of type false. However, the property $mode is declared as type string. Maybe add an additional type check?
Our type inference engine has found a suspicous assignment of a value to a property.
This check raises an issue when a value that can be of a mixed type is assigned to
a property that is type hinted more strictly.
For example, imagine you have a variable $accountId that can either hold an
Id object or false (if there is no account id yet). Your code now assigns that
value to the id property of an instance of the Account class. This class
holds a proper account, so the id value must no longer be false.
Either this assignment is in error or a type check should be added for that assignment.
classId{public$id;publicfunction__construct($id){$this->id=$id;}}classAccount{/** @var Id $id */public$id;}$account_id=false;if(starsAreRight()){$account_id=newId(42);}$account=newAccount();if($accountinstanceofId){$account->id=$account_id;}
