In what scenarios does the case-sensitivity of class_alias() in PHP affect variables, constants, array keys, class properties, and class constants?

The case-sensitivity of class_alias() in PHP affects variables, constants, array keys, class properties, and class constants when using the alias in a case-insensitive manner. To avoid any potential issues, it is recommended to always use the correct case when referencing aliases created with class_alias(). 

// Incorrect usage of class_alias() causing potential issues with case-sensitivity
class_alias('MyClass', 'myclass');
$obj = new myclass(); // This may lead to errors due to case-sensitivity

// Correct usage of class_alias() with the proper case
class_alias('MyClass', 'MyClassAlias');
$obj = new MyClassAlias(); // This will work correctly without any case-sensitivity issues
