Edit report at https://bugs.php.net/bug.php?id=63088&edit=1 ID: 63088 Updated by: laruence@php.net Reported by: daniel dot rudolf at eifel-online dot com Summary: <> operator matches different on CLI -r vs. CLI -f Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: Windows XP PHP Version: 5.3.17 Block user comment: N Private report: N New Comment: or: php.exe -r "var_dump(NULL <> '0');" Previous Comments: ------------------------------------------------------------------------ [2012-09-14 09:42:19] laruence@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 in cmd, you should write two quotes(escape) in the quote string: php.exe -r "var_dump(NULL <> "0");" should be: php.exe -r "var_dump(NULL <> ""0"");" otherwise, I guess CMD will take it as: php.exe -r "var_dump(NULL <> 0);" ------------------------------------------------------------------------ [2012-09-14 09:12:47] daniel dot rudolf at eifel-online dot com Damn... Sorry, I copied the results wrong...
