這是一段有問題的程式碼. . .
把empty()換成isset()...
否則會有notice...
運用三元運算子也就是語句中的 ? : ;
,用empty判斷是否為空
一堆變數判空,非空去空格
? : 這個操作符你去了解一下
這段程式碼就是從post的表單資料中取得資料
主要做了空值校驗第一行程式碼的意思是如果_POST數組裡的taste為空$taste變數賦1 否則為表單資料
其他程式碼差不多這個意思還有就是implode是把傳遞過來的字串按,分割切割成陣列
類似xx?A:B的格式叫做三目運算子
$v=empty(xxxx)?A:B
$v是一個變數
= 號碼是賦值符號
empty(xxxx)? 相當於一個判斷。 empty是判斷是否為空的函數
如果xxxx為空則$V的值賦值為A
如果xxxx不為空則$V的值賦值為B
反對高票答案, 原因如下:
