Doc #76049 [Opn]: ReflectionParameter::__construct() accepts an array for $function

Edit report at https://bugs.php.net/bug.php?id=76049&edit=1 ID: 76049 Updated by: requinix@php.net Reported by: benjamin dot morel at gmail dot com Summary: ReflectionParameter::__construct() accepts an array for $function Status: Open Type: Documentation Problem Package: Reflection related Operating System: N/A PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I would keep "callable" and say that the $function doesn't have to be accessible by the calling scope. If not that, "mixed" and explain in the parameters section. Previous Comments: ------------------------------------------------------------------------ [2018-03-05 12:11:54] benjamin dot morel at gmail dot com True, but it also accepts arrays representing private and non-static methods, which are not callable: --- class Foo { private function bar($baz) {} } function test(callable $function) {} $function = ['Foo', 'bar']; // works as expected echo (new \ReflectionParameter($function, 'baz'))->getName(); // Deprecated: Non-static method Foo::bar() should not be called statically // TypeError: Argument 1 passed to test() must be callable, array given test($function); --- What about callable|array then, with a note about acceptable arrays? ------------------------------------------------------------------------ [2018-03-05 11:27:39] requinix@php.net Valid strings and arrays, \Closures, and objects with __invoke are supported. "callable" would be the most appropriate type. ------------------------------------------------------------------------ [2018-03-05 11:12:47] benjamin dot morel at gmail dot com Description: ------------ The ReflectionParameter constructor is documented as accepting a string only for the first parameter: http://php.net/manual/en/reflectionparameter.construct.php However, as mentioned in a comment on that page, it also accepts an array containing a class name and a method name. Test script: --------------- class Foo { function bar($baz) {} } $r = new ReflectionParameter(array('Foo', 'bar'), 'baz'); echo $r->getName(); Expected result: ---------------- public ReflectionParameter::__construct ( string|array $function , string $parameter ) Actual result: -------------- public ReflectionParameter::__construct ( string $function , string $parameter ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76049&edit=1
