PHP number_format FUNC改變11223344556677到1122334455/66/77

Question

我嘗試這樣做：

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

，但沒有得到結果。請幫忙。

Answer 1

那麼，number_format不是這樣做的。你可以用多種方法自己做，例如：

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

Answer 2

這樣的事情？

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