Description:
------------
As stated in http://bugs.php.net/bug.php?id=17079 and http://news.php.net/article.php?group=php.dev&article=95211 , PHP always resets decimal_point to "." besides your locale "decimal_point".

This breaks backward compatibility, at least with PHP 4.2.3

This is BAD as long as we use na Oracle database with NLS_LANG=Spanish_Spain.WE8ISO8859P1 , needed to output regional chars like ? and ?????. This means that all operations with numerical values returned by a database query (decimal part separated by ',') are broken now.

In my linux:

[root@farm2 root]# export LANG=es_ES
[root@farm2 root]# locale -k decimal_point
decimal_point=","

The script:

<?php

setlocale(LC_ALL, 'es_ES');
$locale_info = localeconv();
echo "decimal_point:   {$locale_info["decimal_point"]}\n";
$value1="1.5";
$value2="1,5";
$res1=$value1*1;
$res2=$value2*1;
echo "Res 1 : $res1 \n";
echo "Res 2 : $res2 \n";

?>

outputs:

decimal_point:   .
Res 1 : 1,5
Res 2 : 1
