php实现四舍五入的方法小结

$number = 1234.5678; 
$nombre_format_francais = number_format($number, 2, ',', ' '); 
// 1 234,57 
$english_format_number = number_format($number, 2, '.', ''); 
// 1234.57 

$number = 1234.5678; 
echo round($number ,2); 
//1234.57 

$formatted = sprintf ("%s有￥%01.2f。",$name, $money); 
echo $formatted;
