哪个PHP函数可以返回当前日期/时间?
当前回答
如果你想获得日期，如12-3-2016，分开每一天，月和年的值，然后复制粘贴以下代码:
$day = date("d");
$month = date("m");
$year = date("y");
print "date" . $day . "-" . $month . "-" . $year;

非常简单的
date_default_timezone_set('Asia/Kolkata');
$date = date('m/d/Y H:i:s', time());
我发现在PHP中获取当前时间的最简单方法是这样的。
//Prints out something like 10:00am Just be sure to set your timezone correctly.
date_default_timezone_set("America/Chicago");
$TIME = date('G:ia');
使用date()和DateTimeInterface::format格式化日期，即date('Y-m-d H:i:s');，你有这些可选格式:

| format character | Description | Example returned values |
|---|---|---|
| Day | --- | --- |
| d | Day of the month, 2 digits with leading zeros | 01 to 31 |
| D | A textual representation of a day, three letters | Mon through Sun |

| l (lowercase 'L') | A full textual representation of the day of the week | Sunday through Saturday |
| N | ISO 8601 numeric representation of the day of the week | 1 (for Monday) through 7 (for Sunday) |
| S | English ordinal suffix for the day of the month, 2 characters | st, nd, rd or th. Works well with j |
| w | Numeric representation of the day of the week | 0 (for Sunday) through 6 (for Saturday) |
| z | The day of the year (starting from 0) | 0 through 365 |
| Week | --- | --- |
| W | ISO 8601 week number of year, weeks starting on Monday | Example: 42 (the 42nd week in the year) |
| Month | --- | --- |
| F | A full textual representation of a month, such as January or March | January through December |
| m | Numeric representation of a month, with leading zeros | 01 through 12 |
| M | A short textual representation of a month, three letters | Jan through Dec |
| n | Numeric representation of a month, without leading zeros | 1 through 12 |
| t | Number of days in the given month | 28 through 31 |
| Year | --- | --- |
| L | Whether it's a leap year | 1 if it is a leap year, 0 otherwise. |
| o | ISO 8601 week-numbering year. This has the same value as Y, except that if the ISO week number (W) belongs to the previous or next year, that year is used instead. | Examples: 1999 or 2003 |
| X | An expanded full numeric representation of a year, at least 4 digits, with - for years BCE, and + for years CE. | Examples: -0055, +0787, +1999, +10191 |
| x | An expanded full numeric representation if requried, or a standard full numeral representation if possible (like Y). At least four digits. Years BCE are prefixed with a -. Years beyond (and including) 10000 are prefixed by a +. | Examples: -0055, 0787, 1999, +10191 |
| Y | A full numeric representation of a year, at least 4 digits, with - for years BCE. | Examples: -0055, 0787, 1999, 2003, 10191 |
| y | A two digit representation of a year | Examples: 99 or 03 |
| Time | --- | --- |
| a | Lowercase Ante meridiem and Post meridiem | am or pm |
| A | Uppercase Ante meridiem and Post meridiem | AM or PM |
| B | Swatch Internet time | 000 through 999 |
| g | 12-hour format of an hour without leading zeros | 1 through 12 |
| G | 24-hour format of an hour without leading zeros | 0 through 23 |
| h | 12-hour format of an hour with leading zeros | 01 through 12 |
| H | 24-hour format of an hour with leading zeros | 00 through 23 |
| i | Minutes with leading zeros | 00 to 59 |
| s | Seconds with leading zeros | 00 through 59 |
| u | Microseconds. Note that date() will always generate 000000 since it takes an int parameter, whereas DateTime::format() does support microseconds if DateTime was created with microseconds. | Example: 654321 |
| v | Milliseconds. Same note applies as for u. | Example: 654 |
| Timezone | --- | --- |
| e | Timezone identifier | Examples: UTC, GMT, Atlantic/Azores |
| I (capital i) | Whether or not the date is in daylight saving time | 1 if Daylight Saving Time, 0 otherwise. |
| O | Difference to Greenwich time (GMT) without colon between hours and minutes | Example: +0200 |
| P | Difference to Greenwich time (GMT) with colon between hours and minutes | Example: +02:00 |
| p | The same as P, but returns Z instead of +00:00 (available as of PHP 8.0.0) | Examples: Z or +02:00 |
| T | Timezone abbreviation, if known; otherwise the GMT offset. | Examples: EST, MDT, +05 |
| Z | Timezone offset in seconds. The offset for timezones west of UTC is always negative, and for those east of UTC is always positive. | -43200 through 50400 |
| Full Date/Time | --- | --- |
| c | ISO 8601 date | 2004-02-12T15:19:21+00:00 |
| r | » RFC 2822/» RFC 5322 formatted date | Example: Thu, 21 Dec 2000 16:01:07 +0200 |
| U | Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) | See also time() |
您可以使用$_SERVER['REQUEST_TIME']变量(自PHP 5.1.0起可用)或time()函数来获取当前的Unix时间戳。
PHP以秒为单位返回当前时间。你需要把它们格式化成你想要的任何格式。
<?php
// time() returns current time in seconds
$in_seconds = time();
// strftime - Format a local time/date according to locale settings
echo strftime("%m/%d/%y", $in_seconds);
?>
