It is not OS dependant as I have the problem with Windows XP. In PHP < 4.3.0 I have a MySQL database with floats. To handle those floats I had to make some convertions (with str_replace) as results were not locale dependant (I use fr_FR). For instance if I had 1.234 stored in db, $row = mysql mysql_fetch_row($handle) would return in $row[0] the value "1.234" and $row[0] * 100 would return 100 whereas of 123,4 (if outputed). In PHP = 4.3.0 I do not need those convertion routines anymore (it was a workaround in my opinion). So starting with PHP 4.3: $a = 1.234 ==> OK whatever locale is $b = "1.234" ==> OK whatever locale is $c = "1,234" ==> NOT OK whatever locale is If I have some user inputs I have to convert from locale representation to number representation before processing them... it would be great to have a function that do the job for us (didn't find one, sorry!)... but maybe that's not the good place to ask for this! ------------------------------------------------------------------------ [2003-01-02 10:13:59] martin at mermaidconsulting dot com I also ran across this problem and have been messing with it for like 3 days before i finally ran across this post. If you do not consider it a bug I would recommend you at least include it in the documentation and make it very clear that you cannot perform calculations using thousands-seperators based on the locale settings. If you have a look at the following sample you can see that user-inputs will get totally messed up in case they use thousand-seperators. <? setlocale(LC_NUMERIC, "en_US") ; // setting the numeric locale to us-conventions setlocale(LC_MONETARY, "en_US") ; // setting the monetary locale to us-conventions $locale_info = localeconv(); echo "mon_decimal_point: {$locale_info["mon_decimal_point"]}<br>"; // displays the monetary decimal point used for the locale echo "mon_thousands_sep: {$locale_info["mon_thousands_sep"]}<br>"; // displays the monetary thousands seperator used for the locale echo "decimal_point: {$locale_info["decimal_point"]}<br>"; // displays the decimal point used for the locale echo "thousands_sep: {$locale_info["thousands_sep"]}<br>"; // displays the thousands seperator used for the locale // defines 2 variables that should be 1000000 and 750000 $a = "1,000,000"; $b = "750,000"; print "A = $a<br>"; print "B = $b<br>"; // performing a simple calculation that illustrates how PHP handles the numbers print "A * 1 = " . ($a*1) . "<br>"; print "B * 1 = " . ($b*1) . "<br>"; ?> Imho there is no point in having locale settings for currencies and numeric values if you cannot use it for doing calculations. Thanks /Martin ------------------------------------------------------------------------ [2002-12-16 19:45:14] [EMAIL PROTECTED] 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 If you switch to a locale where the float separator is ',' then when it comes to output the data back to the user the float decimal point will be depedant on the specified locale. Internally however it'll always be '.'. ------------------------------------------------------------------------ [2002-12-16 08:56:08] jonathan at tricolon dot com > You should not use ',' to represent floats > ALWAYS use '.' regardless of locale. This is exactly the problem. When the locale is changed to Dutch the internal representation of floats is changed. The separator used is changed to ','. This behaviour is incorrect and should be fixed. Check my initial and second post for a detailed description.
