ID: 54547 Comment by: jabakobob at gmail dot com Reported by: peter dot ritt at gmx dot net Summary: wrong equality of string numbers Status: Verified Type: Bug Package: Unknown/Other Function Operating System: linux PHP Version: 5.3.6 Assigned To: dmitry Block user comment: N Private report: N New Comment: The conversion to a number is necessary because programmers don't differentiate between strings and numbers in PHP. Consider the following code: if ($_GET["a"] == $_GET["b"]) echo "a is same as b!"; The result will be the same if the query string is ?a=1&b=1 or ?a=1&b=1.0 or ? a=01&b=1 because PHP is loosely typed. Internally $_GET["a"] and $_GET["b"] are both strings, but we can't do a string comparison. If you want a string comparison, use strcmp. Previous Comments: ------------------------------------------------------------------------ [2012-04-12 13:31:42] Jeff at bobmail dot info I'm confused as to why there is even a conversation around "should we fix this". The data objects are strings. Sure, PHP is "loosely typed" but shouldn't it do the comparison you tell it to do first before attempting anything else? I agree with the previous suggestion: make it a real string comparison and drop the type casting. ------------------------------------------------------------------------ [2012-04-12 06:39:31] paj...@php.net @a at hotmail dot com This is not a support channel, if you need further support for the base ideas about the loosely type nature of PHP, please ask them on one the numerous channels. ------------------------------------------------------------------------ [2012-04-12 06:39:30] paj...@php.net @a at hotmail dot com This is not a support channel, if you need further support for the base ideas about the loosely type nature of PHP, please ask them on one the numerous channels. ------------------------------------------------------------------------ [2012-04-12 06:39:30] paj...@php.net @a at hotmail dot com This is not a support channel, if you need further support for the base ideas about the loosely type nature of PHP, please ask them on one the numerous channels. ------------------------------------------------------------------------ [2012-04-12 05:42:53] a at hotmail dot com @paj...@php.net How about *you* staying polite with your users by actually fixing your bugs?
