There is problem with output from function number_format() 
I have compiled PHP 4.3.0 as Apache module.


print number_format($number,2,"."," ");


if $number is in range 100000 - 999999 or 100000000 - 999999999, output has random character at the begining.

example:
<?

$number=850000000.90;
$number_f=number_format($number,2,"."," ");
for ($i=0;$i<strlen($number_f);$i++) {

    print ord($number_f[$i])." --> ".$number_f[$i]."<br />";

}

print $number_f;
?>

produced:

114 --> r
56 --> 8
53 --> 5
48 --> 0
32 -->
48 --> 0
48 --> 0
48 --> 0
32 -->
48 --> 0
48 --> 0
48 --> 0
46 --> .
57 --> 9
48 --> 0
r850 000 000.90

next run of script add this at the beginning:
72 --> H

Thank you for your help.
