#28243 [Com]: strange parse error

ID: 28243 Comment by: s dot pfalz at teles dot de Reported By: esflightsim at hotmail dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5.0.0RC2 New Comment: Well you are right that this is wrong usage of isset(), but looking at the behavour I would say that this is wrong, PHP 4 reports the correct error like this: PHP Parse error: parse error, expecting T_VARIABLE' or '$'' in /home/siegel/php_tests.php on line 6 But with PHP 5.0.0 you will get now: Parse error: parse error, unexpected ')', expecting T_PAAMAYIM_NEKUDOTAYIM in /html/php_tests.php on line 6 which is in turn a complete wrong error message! here's the code that produces this (I know that it is wrong to isset() a constant, but PHP shouldn't answer with such a error message IMO). Even when one makes errors the interpreter should give accurate responses. ---[SNIP]--- define(SOME_VALUE ,2); if(!isset(SOME_VALUE)) echo("Not found"); else echo("found"); ---[SNAP]---- Previous Comments: ------------------------------------------------------------------------ [2004-05-01 16:42:00] gschlossnagle@php.net Thank you for taking the time to write to us, but this is not a bug.
