Using the code below results into truncation of the floating point numbers if the code is included after the setlocale call.

I saw some old reports of this problem, but the developers claimt to have fixed this.

Tested it on 3 servers, one running php4.2.0 with apache 1.3.24 on gentoo linux 1.1a, the second using apache-1.3.24 with php4.1.2 on redhat 7.1 and the third running apache-1.3.24 with php4.1.2 on slackware 7.
$test = new class1();

$test = new class1();
$test = new class2();

class class1
    function class1()
        $float = 1.1;
$float = 1.1;

class class2
    function class2()
        $float = 1.1;
$float = 1.1;

If you need any extra information, I'll supply you with that :)

yet another setlocale() related issue :(

Same problem with version 4.2.1

Setting the LC_NUMERIC locale category is enough to trigger (or workaround) the bug :

Workaround :

$locale = setlocale( LC_NUMERIC, 0 );
setlocale( LC_NUMERIC, "C" );
// include / include_once / require / require_once...
setlocale( LC_NUMERIC, $locale );
unset( $locale );
