Bug #75912 [Nab]: No name resolution on D::class (even with warnings enabled)

Edit report at https://bugs.php.net/bug.php?id=75912&edit=1 ID: 75912 Updated by: cmb@php.net Reported by: ejrx7753 at gmail dot com Summary: No name resolution on D::class (even with warnings enabled) Status: Not a bug Type: Bug Package: *General Issues Operating System: Mac OS, Ubuntu PHP Version: 7.1.14 Block user comment: N Private report: N New Comment: FTR: this isssue is clearly documented[1]: | The class name resolution using ::class is a compile time | transformation. That means at the time the class name string is | created no autoloading has happened yet. As a consequence, class | names are expanded even if the class does not exist. No error is | issued in that case.

It will not trigger an autoload. Consider instead this snippet: <?php namespace Foo { var_dump(C::class); var_dump(\D::class); } ?> Which prints: string(5) "Foo\C" string(1) "D" ------------------------------------------------------------------------ [2018-02-03 21:38:33] ejrx7753 at gmail dot com Description: ------------ I'm able to enter any random string of characters and add "::class" and it will work fine without error. PHP Documentation clearly states that this ::class feature "allows for fully qualified class name resolution". It should be a fatal error just as with new C(). Quote: "The special ::class constant are available as of PHP 5.5.0, and allows for fully qualified class name resolution at compile, this is useful for namespaced classes:" (http://php.net/manual/en/language.oop5.constants.php) Test script: --------------- <?php error_reporting(E_ALL); ini_set('display_errors', '1'); var_dump(C::class); var_dump(\D::class); Expected result: ---------------- Expected a fatal error Actual result: -------------- string(1) "C" string(1) "D" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75912&edit=1
