我可以將12345678.9輸出成12,345,678.90嗎?_PHP教程

當然可以,PHP中有個函數number_format,函數原型:
string number_format
(
float number,
int decimals,
string dec_point,
string thousands_sep
)
舉個例子:
$num = 12345678.9;
echo number_format($num).'
'; //會4舍5入
echo number_format($num,2).'
';
echo number_format($num,2,':').'
'; //這種寫法是錯誤的
echo number_format($num,2,':','-').'
';
?>
輸出結果為:
12,345,679
12,345,678,90
Warning: Wrong parameter count for number_format() in /data/homepage/test/number_format.php on line 5
