getdate()

(PHP 4, PHP 5, PHP 7)

取得日期／时间信息

说明

返回一个根据$timestamp得出的包含有日期信息的关联数组array。如果没有给出时间戳则认为是当前本地时间。

参数

可选的$timestamp参数是一个integer的 Unix时间戳，如未指定，参数值默认为当前本地时间。也就是说，其值默认为time()的返回值。

返回值

返回一个根据$timestamp得出的包含有日期信息的关联数组array。返回的关联数组中的键名单元有以下几个：

范例

Example #1getdate()例子

以上例程的输出类似于：

Array
(
    [seconds] => 40
    [minutes] => 58
    [hours]   => 21
    [mday]    => 17
    [wday]    => 2
    [mon]     => 6
    [year]    => 2003
    [yday]    => 167
    [weekday] => Tuesday
    [month]   => June
    [0]       => 1055901520
)

• date() 格式化一个本地时间／日期
• idate() 将本地时间日期格式化为整数
• localtime() 取得本地时间
• time() 返回当前的 Unix 时间戳
• setlocale() 设置地区信息

Andre's code will throw an error. for the following line
  
   $d = $todayh[mday];
   $m = $todayh[mon];
   $y = $todayh[year];
"Notice : Undefined constant mday ,mon,year"
As is, it was looking for constants called mday, mon, year etc. When it doesn't find such a constant, PHP interprets it as a string. 
like any other request it should be wrapped in quotes like this
   $d = $todayh['mday'];
   $m = $todayh['mon'];
   $y = $todayh['year'];

In addition to canby23 at ms19 post:
It's a very bad idea to consider day having 24 hours (86400 secs), because some days have 23, some - 25 hours due to daylight saving changes. Using of mkdate() and strtotime() is always preferred. strtotime() also has a very nice behaviour of datetime manipulations: 

I thought best to show a posseble way to go about bypassing the end month issue where the first day in a new month will have the monday of the week that it falls in - in the old month. Use the numbering of days as the constant and work you way from there.

Allot less code makes everyone happy..

another gmgetdate that is a little faster/suscint (no loops).

It's worth noting that this is local time, not UTC/GMT - gmgetdate doesn't exist :(.
The most logical way to handle date arithmetic without hitting DST problems is to work in UTC...

[it's even faster if you use gmmktime instead of strtotime]

Here is another gmgetdate that is a little faster/suscint (no loops). 

It also returns the values in the same order as getdate.
