setlocale() and floatval() duo could break your DB queries in a very simple way:

<?php
setlocale(LC_ALL, 'bg_BG', 'bgr_BGR'); 
echo floatval(0.15); // output 0,15
?>

You would need simple workaround like:

<?php
function number2db($value)
{
    $larr = localeconv();
    $search = array(
        $larr['decimal_point'], 
        $larr['mon_decimal_point'], 
        $larr['thousands_sep'], 
        $larr['mon_thousands_sep'], 
        $larr['currency_symbol'], 
        $larr['int_curr_symbol']
    );
    $replace = array('.', '.', '', '', '', '');

    return str_replace($search, $replace, $value);
}

setlocale(LC_ALL, 'bg_BG', 'bgr_BGR'); 
$testVal = floatval(0.15); // result 0,15
var_dump($testVal, number2db($testVal));

// Result:
// float(0,15) 
// string(4) "0.15" 
?>
