Req #66927 [Opn->Csd]: Request new type operator "exhibits"

Edit report at https://bugs.php.net/bug.php?id=66927&edit=1 ID: 66927 Updated by: kalle@php.net Reported by: rdanner at gmail dot com Summary: Request new type operator "exhibits" -Status: Open +Status: Closed Type: Feature/Change Request Package: *General Issues Operating System: Ubuntu 12.04 LTS PHP Version: 5.4.26 -Assigned To: +Assigned To: kalle Block user comment: N Private report: N New Comment: Or maybe we could instead just modify the instanceof operator to support traits too, as classes/interfaces/traits all internally uses the same symbol table for naming, meaning this is disallowed: trait A {} interface A {} // Error, name is already in use I suggest bringing this up at the mailing list (internals@) and perhaps consider writing an RFC for this that can target 7.2, as its too late for 7.1 Previous Comments: ------------------------------------------------------------------------ [2015-02-08 10:56:48] minecraftshamrock at gmail dot com I agree that such an operator would improve readability. But what would you do with such an operator? Knowing that a class uses a specific trait is nice, but the class might have changed the name or visibility of any of the taits' members. ------------------------------------------------------------------------ [2014-03-18 17:29:13] rdanner at gmail dot com Description: ------------ Much like the "instanceof" operator can be used to evaluate if a class is and instance of (or descendant of) a particular class, an "exhibits" keyword would be useful for evaluating if a class exhibits a particular trait: if ($baz exhibits someTrait) {} Test script: --------------- //Currently, this can be done with something along the lines of $ob = new someClass; // see if $ob is an instance of a class that exhibits the "neato" trait if (class_exists('someClass') and in_array('neato', class_uses($ob)) { // it does! } //but this would be much cleaner as: if ($ob exhibits neato) { // yup! } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66927&edit=1
