php - php number_format 函数将 11223344556677 更改为 1122334455/66/77

Question

我试过这个：

$number = 11223344556677;
echo number_format($number,2,'/',2,'/','');

但没有得到结果。请帮忙。

Answer 1

好吧，number_format不是为了这样做。您可以通过多种方式自己完成，例如：

echo preg_replace('/^(\d*)(\d{2})(\d{2})$/', '$1/$2/$3', $number);

Answer 2

像这样的东西？

$formatted_number = preg_replace('(\d+?)(\d\d)(\d\d)','$1/$2/$3',$number);
