Application of the Php-date (), Time () function

This article is to share the content of PHP in the date () and time () function of the application, the need for friends can refer to

1, the current timestamp (unit: seconds)

Description: The time () function returns the number of seconds of the current period from the Unix era (January 1 1970 00:00:00 GMT)
Syntax: Time ()
Give me a chestnut:

Time (): Returns the current time of the Unix timestamp echo times ();//For example: 1516332756

2. Ask for the current date

Description: the date () function is used to format the time/date.
Syntax: string Date (string

Timestamp])
Parameters:
Format required. Specifies the format of the timestamp.
Timestamp is optional. Time stamp is specified. The default is the current date and time.
Give me a chestnut:

The following lines of code will have the same output (the style may be different) echo date (' y-m-d h:i:s '),//2018-01-19 11:56:08echo date (' y-m-d h:i:s ', Time ()),//2018-01-19 11:56:08echo date (' Ymd his ', Time ()),//20180119 115608echo date (' Y.m.d h:i:s ', Time ()),//2018.01.19 11:56:08

3, today, yesterday, tomorrow, the time stamp of the simple implementation method

Echo strtotime (' Now '), ' <br> ';//Present: 1516334071echo strtotime (' Today '), ' <br> ';//Today: 1516291200echo Strtotime (' Tomorrow '), ' <br> ';//Tomorrow: 1516377600echo strtotime (' Yesterday '), ' <br> ';//yesterday: 1516204800echo $ Time_remain=strtotime (' Tomorrow ')-time ();//number of seconds left today-output: 43362

4. How to achieve the date of recent days

echo "Today:". Date ("y-m-d"). " <br> "echo" Yesterday: ". Date (" Y-m-d ", Strtotime (" 1 day ")," <br> ";     echo "Tomorrow:". Date ("Y-m-d", Strtotime ("+1 Day")). " <br> "echo" A week ago: ". Date (" Y-m-d ", Strtotime (" 1 Week "))." <br> "echo" A week later: ". Date (" Y-m-d ", Strtotime (" +1 Week "))." <br> "echo" One months ago: ". Date (" Y-m-d ", Strtotime (" Last month ")." <br> ";     echo "One months later:". Date ("Y-m-d", Strtotime ("+1 Month")). " <br> "; echo "Next week Four:". Date ("Y-m-d", Strtotime ("next Thursday")). " <br> "echo" Ten years later: ". Date (" Y-m-d ", Strtotime (" +10 Year "))." <br> "; The function of the Strtotime () function is to parse a datetime description into a Unix timestamp

5. Today is the day of the week

Get the day of the Week (English) echo date ("L");//Can get English for the week such as Sundayecho date ("w");//This can be obtained for the number of weeks such as ..., note 0 is Sunday. Get today's Day of the Week (Chinese) $weekarray =array ("th", "One", "two", "three", "four", "five", "six"); Echo "Week". $weekarray [Date ("W")];
