问题描述
我想编写一些代码来判断我的日期是否需要st，nd rd或
。 />
虽然下面的代码有效，但我确信有更好的方法....
if（（$ daterep ==" 1"）| |（$ daterep ==" 21"）||（$ daterep ==" 31"））{
$ letters =" st";
} elseif（（$ daterep ==" 2"）||（$ daterep ==" 22"））{
$ letters =" nd";
} elseif（（$ daterep ==" 3"）||（$ daterep ==" 23"））{
$ letters =" rd";
} else {
$ letters =" th";
}
我试过：
if（$ daterep ==" 1" ||" 21" ||" 31"）{... etc
但它没有工作...虽然我不明白为什么？
我把$ daterep投入一个字符串，但现在我发现我可以把它留下来
一个人... ..
任何建议如何让这段代码更顺畅？

Hi,
I was wanting to write some code to work out whether I needed st, nd rd or
th in my dates.
While the code below works, I am certain that there is a better way....
if (($daterep == "1") || ($daterep == "21") || ($daterep == "31")){
$letters = "st";
} elseif (($daterep == "2") || ($daterep == "22")){
$letters = "nd";
} elseif (($daterep == "3") || ($daterep == "23")){
$letters = "rd";
} else {
$letters = "th";
}
I tried:
if ($daterep == "1" || "21" || "31") { ... etc
but it did not work... I don''t understand why though?
I cast $daterep into a string, but now I find that I could have left it
alone....
Any suggestions as to how to get this code working a bit smoother?
Robert
