Contributors to HEPTAconnect packages have one breaking change complexity layer less to work on. It also has the same developer experience across PHP versions. This allows setting parameters by name via using their respective setter. We already use this occasionally with a trend towards this. This feature can be replicated to a certain degree with parameter classes the only contain the data for a method call in a single object, and therefore is not a language feature we depend on. This includes to wrap calls for func_get_arguments in an array_values or similar approaches to remove names from parameters. We do not support this feature and claim the argument names as private API. When using PHP >=8.0 function arguments are not just positional but also associative and keyed by their name depending on the callers function calling behaviour. With the implementation of this feature a language aspect changes how public API is perceived. This way, callers like g and g's clients have many options, and furthermore, callers always know how to omit arguments so they can omit one in the middle of the parameter list.Portal dependency injection implementationįilesystem abstraction with stream wrapperĪt one point the old RFC for named arguments got an update, has been approved and implemented. The best approach, it seems to me, is to always use a sentinel like null as the default value of an optional argument. Suppose you want to call the function f many times from function g, allowing the caller of g to specify if f should be called with a specific value or with its default value: The utility of the optional argument feature is thus somewhat diminished. In function calls, PHP clearly distinguishes between missing arguments and present but empty arguments. To experiment on performance of pass-by-reference and pass-by-value, I used this script.
