我在本地wamp設置上運行php 5.3.5。我正在運行一個簡單的代碼。php date_diff問題。得到空白的結果
echo "<br/>DEBUGGING";
echo "<br/>===========";
echo "<br/>Date: ".$date;
echo "<br/>Lead Days: ".$lead_days;
echo "<br/>Date diff: ".var_dump(date_diff((int)$date, (int)$lead_days))." difference";
但輸出是:
DEBUGGING
===========
Date: 2012-08-31
Lead Days: 2012-09-05
boolean false
Date diff: difference
date_diff似乎返回false。我已經嘗試了沒有var_dump和沒有int鑄造,但它總是空白,但它工作,如果我上傳到我的網絡服務器。任何想法這裏有什麼不對?
