Php 如何使用IF语句以1的增量自动增加数字？,php,Php,我试图回应一个可变的数字，但我不确定最好的方法。我的问题是：我有一系列的“如果”条件，我相应地回显一个变量 if ($month == "8" || $month == "9" || $month == "10") { $comingseason = 'winter'; $elementsDue = "Due October 31, " . $year . ", for our " . $comingseason . " issue No. 9"; } else

我试图回应一个可变的数字，但我不确定最好的方法。我的问题是：

我有一系列的“如果”条件，我相应地回显一个变量

   if ($month == "8" || $month == "9" || $month == "10") {
    $comingseason   = 'winter';
    $elementsDue    = "Due October 31, " . $year . ", for our " . $comingseason . " issue No. 9";
}
else if ($month == "11" || $month == "12" || $month == "1") {
    $comingseason   = 'spring';
    $elementsDue    = "Due January 31, " . ++$year . ", for our " . $comingseason . " issue No. 9";
}
else if ($month == "2" || $month == "3" || $month == "4") {
    $comingseason   = 'summer';
    $elementsDue    = "Due April 30, " . $year . ", for our " . $comingseason . " issue No. 9";
}
else if ($month == "5" || $month == "6" || $month == "7") {
    $comingseason   = 'fall';
    $elementsDue    = "Due July 31, " . ++$year . ", for our " . $comingseason . " issue No. 9";
}

我想知道我将如何用下一个增量++1替换“第9期”中的数字，以输出“10”？我不想每次都要回到代码中，输入下一期的编号。我希望这个数字能自行增加，基本上是每个季度都会增加，就像你在下面看到的那样

我在考虑一个php会话，但据我所知，它不会是永久的。我需要在用户结束会话后保留该号码

我怎样才能做到这一点

也许你在找这个

说明：添加一个整数变量，比如$issuNo，然后再添加该变量的初始值。然后，在if/else条件块之后，放入类似$issuNo++的增量变量，然后最好编写一个程序，稍后继续执行if/else语句

$issuNo = 9;     
if ($month == "8" || $month == "9" || $month == "10") {
        $comingseason   = 'winter';
        $elementsDue    = "Due October 31, " . $year . ", for our " . $comingseason . " issue No. ".$issuNo;
    }
    else if ($month == "11" || $month == "12" || $month == "1") {
        $comingseason   = 'spring';
        $elementsDue    = "Due January 31, " . ++$year . ", for our " . $comingseason . " issue No. ".$issuNo;
    }
    else if ($month == "2" || $month == "3" || $month == "4") {
        $comingseason   = 'summer';
        $elementsDue    = "Due April 30, " . $year . ", for our " . $comingseason . " issue No. ".$issuNo;
    }
    else if ($month == "5" || $month == "6" || $month == "7") {
        $comingseason   = 'fall';
        $elementsDue    = "Due July 31, " . ++$year . ", for our " . $comingseason . " issue No. ".$issuNo;
    }
$issuNo++;

这似乎是一个很简单的问题。我建议读一本好的入门级PHP编程书。话虽如此，您需要设置

while

循环和一些嵌套的

if-else

条件

$month = 0;

while ($month < 12) {
    $month++;

    If ($month > 7 && $month < 11)
    { 
        $comingsoon = "winter";
    }
    elseif 
    {
        some logic
    }
    elseif
    {
        some logic
    }
    else
    {

    }
} # end of while loop

$month=0；
而（$month<12）{
$month++；

在我看来，问题是年和季度的函数：从某个基准年/季度开始，每个季度有一个问题。因此，类似这样的东西应该会自动计算它（您必须使用$base_year和$base_qtr使其与您的发行编号匹配）

如果这是您正在寻找的：

$year = '2015';

 if ($month == "8" || $month == "9" || $month == "10") {
    $comingseason   = 'winter';
 echo   $elementsDue    = "Due October 31, " . $year . ", for our " . $comingseason . " issue No. $issue";
}
else if ($month == "11" || $month == "12" || $month == "1") {
    $comingseason   = 'spring';
        $issue = $issue + 1;

echo    $elementsDue    = "Due January 31, " . ++$year . ", for our " . $comingseason . " issue No. $issue";
