Bug #9186 Updated: string compare with "==" does not work correctly

ID: 9186 Updated by: danbeck Reported By: tom.anheyer@berlinonline.de Old-Status: Analyzed Status: Closed Bug Type: Documentation problem Operating system: PHP Version: 4.0.4pl1 Assigned To: Comments: I'm not sure why this is still open as a documentation bug. The string behavior is documented in: http://www.php.net/manual/en/language.types.string.php and the == and === behavior is documented in: http://www.php.net/manual/en/language.operators.comparison.php Previous Comments: --------------------------------------------------------------------------- [2001-02-15 05:38:18] tom.anheyer@berlinonline.de The conversation is useful. I know this because HTML form parameters, MySQL result sets are strings even if they are represent numbers. But there some cases for which the conversation is not useful. If the result is MAXINT, MININT or NaN, it would be better not converting the operands and making a string comparision. A warning message whould be also useful. --------------------------------------------------------------------------- [2001-02-15 05:25:09] hholzgra@php.net this autoconversion is usefull when dealing with html form input (for which php is used every once in a while afaik :) as html has no numric input elements, just text maybe it would make sense to have this behaviour configurable in the ini file, but i'm afraid that this would only increase the WTF factor even more --------------------------------------------------------------------------- [2001-02-15 05:07:35] tom.anheyer@berlinonline.de Ok, I accept this. But I don't think that is a good idea to compare apples with pears with the answer 'yes they are fruit' without any warning. --------------------------------------------------------------------------- [2001-02-15 04:32:00] zeev@php.net Ok, it should remain open as a documentation problem... --------------------------------------------------------------------------- [2001-02-15 04:31:01] zeev@php.net This is a defined behavior (and does have strong reasons). It's not a bug. If you're interested in a byte-by-byte string comparison, you should use strcmp(). --------------------------------------------------------------------------- The remainder of the comments for this report are too long.
