如何获取JSON对象数组中的下个月日期? [英] How to get next month dates in JSON object array?
问题描述
我有一个 php代码，如下所示，其中在每个月的第一天，我将第二个JSON对象数组(next_month)内容复制到第一个JSON对象中数组(当前月).
在第二个JSON对象数组(next_month)中，我想要下个月的日期.这也将在每个月的第一天发生.目前，我正在存储 nada .让我们假设今天是11月1日.
php代码:
$ value = json_decode(file_get_contents('../hyt/dates.json'));如果((date('j')== 1)){$ month = 11;$ year = date('Y');$ current_month_days =(date('t'，strtotime($ year.'-'.$ month.'-01'))));$ next_month_days =(date('t'，strtotime($ year.'-'.($ month + 1).'-01'))));$ value-> current_month = $ value-&next_month;//Y行$ value-> next_month = array_fill(0，($ next_month_days)，nada);//Z行} JSON (dates.json)的当前外观如下所示:
{"current_month":["2020-10-01"，"2020-10-02"，"2020-10-03"，"2020-10-04"，"; 2020-10-05"，"2020-10-06"，"2020-10-07"，"2020-10-08"，"2020-10-09"，"2020-10-"10"，"2020-10-10"，"2020-10-12"，"2020-10-13"，"2020-10-14"，"2020-10-15"，"2020"2020-10-16"，"2020-10-17"，"2020-10-18"，"2020-10-19"，"2020-10-20"，"2020-10-21"；，"2020-10-22"，"2020-10-23"，"2020-10-24"，"2020-10-25"，"2020-10-26"，"2020"-10-27"，"2020-10-28"，"2020-10-29"，"2020-10-30"，"2020-10-31"]，下个月":["2020-11-01"，"2020-11-02"，"2020-11-03"，"2020-11-04"，"2020-11-05"，"2020-11-06"，"2020-11-07"，"2020-11-08"，"2020-11-09"，"2020-11-11"，"2020-11-11"，"2020-11-12"，"2020-11-13"，"2020-11-14"，"2020-11-15"，"2020-11-16"，"2020-11-17"，"2020-11-18"，"2020-11-19"，"2020-11-20"，"2020-11-21"，"2020-11"-22"，"2020-11-23"，"2020-11-24"，"2020-11-25"，"2020-11-26"，"2020-11-27"，"; 2020-11-28"，"2020-11-29"，"2020-11-30"]} 问题陈述:
我想知道应该在第Z行进行哪些更改，以便在第二个JSON对象数组中能够获取下个月的日期.目前，我正在存储 nada .
在成功执行Y行和Z行之后的11月1日的第一天，我想要在JSON中显示的内容是:
{"current_month":["2020-11-01"，"2020-11-02"，"2020-11-03"，"2020-11-04"，"; 2020-11-05"，"2020-11-06"，"2020-11-07"，"2020-11-08"，"2020-11-09"，"2020-11-"11"，"2020-11-11"，"2020-11-12"，"2020-11-13"，"2020-11-14"，"2020-11-15"，"2020-11-15"2020-11-16"，"2020-11-17"，"2020-11-18"，"2020-11-19"，"2020-11-20"，"2020-11-21";，"2020-11-22"，"2020-11-23"，"2020-11-24"，"2020-11-25"，"2020-11-26"，"2020"-11-27"，"2020-11-28"，"2020-11-29"，"2020-11-30"]，下个月":["2020-12-01"，"2020-12-02"，"2020-12-03"，"2020-12-04"，"2020-12-05"，"2020-12-06"，"2020-12-07"，"2020-12-08"，"2020-12-09"，"2020-12-11"，"2020-12-11"，"2020-12-12"，"2020-12-13"，"2020-12-14"，"2020-12-15"，"2020-12-16"，"2020-12-17"，"2020-12-18"，"2020-12-19"，"2020-12-20"，"2020-12-21"，"2020-12"-22"，"2020-12-23"，"2020-12-24"，"2020-12-25"，"2020-12-26"，"2020-12-27"，"2020"; 2020-12-28"，"2020-12-29"，"2020-12-30"，"2020-12-31"]} 这是我尝试过的:
这是我在Z行尝试过的方法，但它仅将今天的日期存储在JSON对象数组中.
$ value-> next_month = array_fill(0，($ next_month_days)，date("Y-m-d")); //Z线
您正在使用 array_fill ，该代码用于使用相同的值填充至少一部分数组>.我建议使用简单的for循环:
$ next_month_array = [];$ next_month = $ month<12?$ month + 1:1;$ year = date('Y');for($ day_counter = 1; $ day_counter< = $ next_month_days; $ day_counter ++){$ next_month_array [] ="$ year- $ next_month- $ day_counter";}$ value-> next_month = $ next_month_array; I have a php code as shown below in which on the 1st day of every month, I am copying 2nd JSON object array (next_month) content into 1st JSON object array (current_month).
In the 2nd JSON object array (next_month), I want to have next month dates. That will also happen on the 1st day of every month. Currently I am storing nada. Let us suppose that today is 1st day of November.
php code:
$value = json_decode(file_get_contents('../hyt/dates.json'));
if ((date('j') == 1)) {
$month = 11;
$year = date('Y');
$current_month_days = (date('t', strtotime($year . '-' . $month . '-01')));
$next_month_days = (date('t', strtotime($year . '-' . ($month + 1) . '-01')));
$value->current_month = $value->next_month; // Line Y
$value->next_month = array_fill(0, ($next_month_days), nada); // Line Z
}
The current look of JSON (dates.json) is shown below:
{"current_month": ["2020-10-01", "2020-10-02", "2020-10-03", "2020-10-04", "2020-10-05", "2020-10-06", "2020-10-07", "2020-10-08", "2020-10-09", "2020-10-10", "2020-10-10", "2020-10-12", "2020-10-13", "2020-10-14", "2020-10-15", "2020-10-16", "2020-10-17", "2020-10-18", "2020-10-19", "2020-10-20", "2020-10-21", "2020-10-22", "2020-10-23", "2020-10-24", "2020-10-25", "2020-10-26", "2020-10-27", "2020-10-28", "2020-10-29", "2020-10-30","2020-10-31"],
"next_month": ["2020-11-01", "2020-11-02", "2020-11-03", "2020-11-04", "2020-11-05", "2020-11-06", "2020-11-07", "2020-11-08", "2020-11-09", "2020-11-11", "2020-11-11", "2020-11-12", "2020-11-13", "2020-11-14", "2020-11-15", "2020-11-16", "2020-11-17", "2020-11-18", "2020-11-19", "2020-11-20", "2020-11-21", "2020-11-22", "2020-11-23", "2020-11-24", "2020-11-25", "2020-11-26", "2020-11-27", "2020-11-28", "2020-11-29", "2020-11-30"] }
Problem Statement:
I am wondering what changes I should make at Line Z so that in the second JSON object array, I am able to get next month dates. At present, I am storing nada.
The content which I want in the JSON on the 1st day of November month after successful execution of Line Y and Line Z is:
{"current_month": ["2020-11-01", "2020-11-02", "2020-11-03", "2020-11-04", "2020-11-05", "2020-11-06", "2020-11-07", "2020-11-08", "2020-11-09", "2020-11-11", "2020-11-11", "2020-11-12", "2020-11-13", "2020-11-14", "2020-11-15", "2020-11-16", "2020-11-17", "2020-11-18", "2020-11-19", "2020-11-20", "2020-11-21", "2020-11-22", "2020-11-23", "2020-11-24", "2020-11-25", "2020-11-26", "2020-11-27", "2020-11-28", "2020-11-29", "2020-11-30"],
"next_month": ["2020-12-01", "2020-12-02", "2020-12-03", "2020-12-04", "2020-12-05", "2020-12-06", "2020-12-07", "2020-12-08", "2020-12-09", "2020-12-11", "2020-12-11", "2020-12-12", "2020-12-13", "2020-12-14", "2020-12-15", "2020-12-16", "2020-12-17", "2020-12-18", "2020-12-19", "2020-12-20", "2020-12-21", "2020-12-22", "2020-12-23", "2020-12-24", "2020-12-25", "2020-12-26", "2020-12-27", "2020-12-28", "2020-12-29", "2020-12-30", "2020-12-31"] }
This is what I have tried:
This is what I have tried at Line Z but its storing only today's date in JSON object array.
$value->next_month = array_fill(0, ($next_month_days), date("Y-m-d")); // Line Z
You are using array_fill, which is used to fill at least part of an array with the same value. I would recommend using a simple for loop:
$next_month_array = [];
$next_month = $month < 12 ? $month + 1 : 1;
$year = date('Y');
for($day_counter = 1; $day_counter <= $next_month_days; $day_counter++) {
$next_month_array[] = "$year-$next_month-$day_counter";
}
$value->next_month = $next_month_array;
