Edit report at https://bugs.php.net/bug.php?id=71620&edit=1 ID: 71620 Updated by: requinix@php.net Reported by: miracle at rpz dot name Summary: strange behavour of parser and exception's handler Status: Open Type: Bug Package: Scripting Engine problem Operating System: Linux PHP Version: 7.0.3 Block user comment: N Private report: N New Comment: https://3v4l.org/K4KhS The deprecated constructor problem is being detected at compile time - before any code has been executed. You can test this by return;ing at the very beginning of the file. https://3v4l.org/tL7G2 By throwing the exception, the file is not executed at all and thus the constant will not be define()d. The same problem exists if you use a variable: https://3v4l.org/oQlFm With that said, given that the class exists, I would expect const to work too. (Or neither.) But it does not: https://3v4l.org/h02r8 Additionally, wrapping the class definition in an if(true) causes both the class and constant to be undefined, which is what I would have expected from the original code: https://3v4l.org/QdWiC Previous Comments: ------------------------------------------------------------------------ [2016-02-17 21:11:50] miracle at rpz dot name Description: ------------ Legacy code use PEAR's classes with php4-style constructor. Usualy In same file defined several global constants used in class. When this file included, then engine throw warning about deprecated constructor. After catch this "exception" we have new class (hooray!) and undefined constants from same file... Test script: --------------- foo.php: <?php define('LOST_CONSTANT', 42); class Foo { public function foo() { // throw notice about deprecated constructor } } ?> main.php: <?php set_error_handler(function($errno, $errstr) { throw new Exception($errstr, $errno); // convert error to exception }); try { include 'foo.php'; } catch (Exception $e) { printf("error %d with message: %s\n", $e->getCode(), $e->getMessage()); } var_dump( class_exists('foo'), // exists! defined('LOST_CONSTANT') // where is my constant ); Expected result: ---------------- error 8192 with message: Methods with the same name as their class will not be constructors in a future version of PHP; Foo has a deprecated constructor main.php:14: bool(true) main.php:14: bool(true) Actual result: -------------- error 8192 with message: Methods with the same name as their class will not be constructors in a future version of PHP; Foo has a deprecated constructor main.php:14: bool(true) main.php:14: bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71620&edit=1
