我正在尝试回显一个变量数，但我不确定最好的方法。我的问题是:
我有一系列'IF'条件，并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 " . $comingseason . " issue No. 9";
}
我想知道如何用下一个增量++1替换'issue No. 9'中的数字以输出'10'?我不想每次都回到代码中输入下一期的编号。我希望这个数字能自己增加，基本上是每个季度都增加，就像你看到的那样。
我正在考虑一个php会话，但据我所知，这将不是永久的。我需要这个数字即使在用户结束会话后也保持不变。
我怎样才能做到这一点?
在我看来，问题#是年和季度的函数:从某个基准年/季度开始，每个季度有一个问题。因此，像这样的东西应该自动计算它(您必须使用$base_year和$base_qtr来使其与您的问题编号匹配)。
function currentIssue() {
$base_year = 2014;
$base_qtr = 2;
$now_year = intval(date('Y');
$now_qtr = ceil(intval(date'm')/3);
return ($now_year - $base_year)*4 + ($now_qtr - $base_qtr);
}
好吧，这似乎是一个非常简单的问题。我建议阅读一本好的入门级PHP编程书籍。话虽如此，您需要设置一个while循环和一些嵌套的if else条件。
$month = 0;
while ($month < 12) {
$month++;
If ($month > 7 && $month < 11)
{
$comingsoon = "winter";
}
elseif
{
some logic
}
elseif
{
some logic
}
else
{
}
} # end of while loop
我有意把剩下的代码留给你写。这将是一个很好的练习，让你学习一些编码:)祝你好运!
也许你正在寻找这个，
解释:添加一个整数变量，比如$issuNo，然后添加一个初始值。然后在if/else条件块后面加上增量变量，比如$ issuno++，然后你最好编写一个程序，可以在后面继续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++;
如果这是你正在寻找的:
<?php
$month = '3';
$year = '2015';
$issue = 9;
if ($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. $issue";
}
else if ($month == "2" || $month == "3" || $month == "4") {
$comingseason = 'summer';
$issue = $issue + 2;
echo $elementsDue = "Due April 30, " . $year . ", for our " . $comingseason . " issue No. $issue";
}
else if ($month == "5" || $month == "6" || $month == "7") {
$comingseason = 'fall';
$issue = $issue + 3;
echo $elementsDue = "Due July 31, " . ++$year . ", for our " . $comingseason . " issue No. $issue";
}
?>
