Status: Not a bug Type: Bug Package: *General Issues Operating System: debian wheezy PHP Version: 5.5.11 Block user comment: N Private report: N New Comment: my mistake ... thank you for your comment ... i am appreciate for that ... Previous Comments: ------------------------------------------------------------------------ [2014-04-23 18:25:47] johannes@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is a nifty case: Only "simple" classes are fully available after compile time, classes with "complexer" things (interface,traits, ...) will be bound and made available at runtime in the place where they are declared, else constructs like <?php include 'someinterface.php'; class C implements someinterfae {} ?> won't work. same with traits. ------------------------------------------------------------------------ [2014-04-23 09:57:26] php at sunyanzi dot me Description: ------------ function class_exists returns wrong result when a class used traits ... in clear way ... just see code below ... Test script: --------------- <?php var_dump( class_exists( 'baz' ) ); // true var_dump( class_exists( 'bar' ) ); // false trait foo { } class bar { use foo; } class baz { } var_dump( class_exists( 'bar' ) ); // true Expected result: ---------------- bool(true) bool(true) bool(true) Actual result: -------------- bool(true) bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67114&edit=1
