I get curious values running the following script on 5.3.3 (ubuntu) and 5.4.7 (win): <?php setlocale(LC_ALL, 'en_EN'); $x = 0.1; echo $x; echo '<br />'; setlocale(LC_ALL, 'de_DE'); $x = 0.1; echo $x; ?> 5.3.3 (ubuntu) gives me the following: 0.1 0,1 5.4.7 (win): 0.1 0.1 That can't be the expected behavior if there was no change between those versions? ------------------------------------------------------------------------ [2012-06-22 11:05:53] schindler dot andor at empo dot deletethis dot hu Yes, this is not a bug. This is a huge epic fail. This is a great example, why people hate PHP. ------------------------------------------------------------------------ [2004-10-23 16:58:47] erki at lap dot ttu dot ee Having the setlocale function in string.c execute if ((lc.decimal_point)[0] != '.') { /* set locale back to C */ setlocale(LC_NUMERIC, "C"); } is not a solution. The particular "fix" broke other things. In many countries, comma is used as a decimal separator. Case in point: 3 weeks ago, a certain financial database of a major telco company in Europe was upgraded to use PHP 4.3.8 (formerly 4.2.2). The system uses Oracle for persistence, where the decimal separator is a comma, as is a custom in that country. So numbers came in from Oracle, and then PHP was unable to process them correctly. For example, if a client had a debt of 25,12?, and the client paid 5?, then the comparison ($paid_amount > $debt) said incorrectly that the paid amount was more than the debt. Result: hundreds of wasted man-hours. In the end we recompiled PHP without that "fix". ------------------------------------------------------------------------ [2003-07-05 06:13:19] dMNz at one dot lt am pabandymuj.. ------------------------------------------------------------------------ [2003-03-24 10:18:13] moriyoshi@php.net Related discussion: http://news.php.net/article.php?group=php.dev&article=95211 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
